Cat and Robbie were dancing backstage (near each other) during Tori's performance in the big Showcase.
When Cat and Robbie are sent to get Tori and Andréand tell them to come back to class, Rex makes fun of Cat saying, "And you wanted a date to the prom last year but you didn't get one, did you?" to which Cat turns to Robbie, shrieking, "Tell your puppet to quit being mean to me!"
Robbie yells at Rex when he insults Cat.
Cat and Robbie are both examples Tori uses to explain why Hollywood Arts is not a normal school, showing that both Cat and Robbie are seen the same way in a stereotypical crowd, making them compatible.
After Cat loses the Alphabet Improv game and takes the piece of candy Sikowitz gives her, she sits down happily next to Robbie.
Robbie smiles at Cat when she sits down next to him.
The Bird Scene
Cat thinks it's gross that Rex (possibly Robbie) hits on every girl in school.
Rex states that he never hits on Cat. It's known that Robbie thinks of Rex, his puppet, as a separate person, so a possible reason why Rex never hits on Cat is because Robbie doesn't like it when other guys hit on Cat. Another possibility is that since Rex may represent another part of Robbie, Robbie may just want to respect Cat since she thinks its gross, or is too shy to make a move, even through his puppet.
Cat seems offended when Rex says that he never hits on her, as she probably knows that Rex and Robbie are practically the same person. Cat might be upset that Robbie doesn't flirt with her and even seems worried that Robbie might not be attracted to her.
Cat looks with concern at André and Robbie walking into the classroom, after their ballet incident.
Cat is the only one who pays attention to Robbie and Trina's situation. She seems sort of frustrated that Robbie is so focused on trying to get Trina to go out with him, possibly a sign of jealousy.
Cat and Robbie sit together alone at lunch.
Robbie comes to Cat to talk about his "relationship" with Trina, possibly to make her jealous.
After Robbie stalks Trina for a while (because he believes their stage kiss was real), Cat tries to make him understand that it was just a stage kiss. When he says that girls can't fake that kind of passion, Cat interrupts him by kissing him. She may be using the excuse of trying to proving a point as an opportunity to kiss him because she likes him, she may also have been jealous that Robbie liked Trina.
After the kiss, Robbie asks Cat to meet his parents, and she almost chokes on her carrot.
The way he reacts to Cat's kiss means that she either showed more 'passion' then Trina did or that he likes her better (Robbie acts shocked when Trina kissed him, but he asks if Cat could meet his parents, as if they were already in a relationship).
After Robbie asked Cat to meet his parents they continue to sit next to each other.
The Birthweek Song
The sub-plot focuses on Robbie and Cat helping Robbie's Grandmother with her computer.
This episode takes place right after Stage Fighting, the episode in which Cat kisses Robbie. Notably, after the kiss, Robbie states that he wants Cat to meet his parents. This trip to his Grandmother's house could be a venture for approval of Cat, after developing feelings for her.
After Cat says to Tori, "What are you doing?" and she doesn't respond, Cat and Robbie look at each other and Cat smiles.
Whilst Tori is trying to figure out what to get Trina for her birthweek, Robbie and Cat are walking down the stairs when Rex then says something disrespectful. Cat helps Robbie give Rex a time out by putting him in Robbie's backpack.
Robbie and Cat were going to get iced coffee together.
After Robbie says that he has to help his grandma and asks the others to come with him, only Cat volunteers (because she likes it when elderly people shake when they pour their juice). She also may have wanted to spend more time with Robbie.
After Cat says juice, Robbie gives a slight grin to her comment maybe implying that he was happy she said she would go with him.
Robbie's grandma keeps criticizing Cat throughout the episode and when she first sees Cat, she thinks that she is Robbie's girlfriend. When he denies this, she says, "Good, you can do better." Cat gets offended a lot throughout this episode, possibly because she thinks that she and Robbie would not be a bad match.
During class, when Robbie is about to start his presentation on Vaudeville, he says, "Hello, everybody." Cat is the only one who says "Hi" back to him.
When Robbie becomes embarrassed when his grandma attempts to video chat with him in front of the class, Cat laughs at him along with the rest of class, but she says she thinks it's cute.
When Cat sees Robbie's grandma's apartment, she says to him, "You said you were taking me to play baby golf!" in a disappointed tone. She may have come because she thought she and Robbie would be going alone to play baby golf together, like a date.
Robbie knows that Cat likes to play baby golf as he tricked Cat into going to his grandma's house a second time.
When Cat was sad that they weren't going to play baby golf Robbie said that they were only going to be there for a half hour, maybe implying that they would play baby golf after.
Robbie's grandma thinks that Robbie and Cat are dating.
On their last visit to his grandma's house, she says that she doesn't want to go in there and be made fun of. However Robbie insists that she comes in, and pulls her inside by the arm. When his grandma makes fun of her again, she turns to leave, however Robbie grabs her wrist and pulls her back. His grandma and Cat continue to fight, so Robbie cuts a wire to disable the Internet in his Grandma's house, claiming the company shut it down and the Internet no longer exists. He takes Cat and they both run out of the apartment while holding hands.
When Cat and Robbie's grandma are fighting, Robbie's grandmother says, "Over my dead body, would I let my grandson ever marry..." (implying that she thinks that they're dating).
When Cat is at lunch, Cat giggles flirtatiously at Robbie whilst he's talking to his grandmother on the phone.
Cat gets upset when Robbie points out that she doesn't take criticism well, possibly because she doesn't want him to see her in an unfavorable light.
Robbie apologizes, and Cat happily accepts his apology for "offending her" .
Robbie thought to warn Cat about his grandma being critical because he knows Cat doesn't take criticism very well.
When Robbie comes up to do his report, there's a shot of Cat smiling sweetly at him.
Robbie looks at Cat with an astonished face when his grandma exclaims that she doesn't want him to end up with "one of those" (Cat); he looks offended his grandma would say that about Cat.
After Robbie grabs her the first time, Cat looks like she wants to turn and leave again, but sighs and decides to give in and stay.
Cat tells Robbie that his grandma hates her, and Robbie says, "She doesn't hate you."
Cat looks sort of exasperated when Robbie's grandma tries to set Robbie up with Brenda.
Even though just a couple of moments before she was arguing with Robbie's grandma, she looks concerned when Robbie yells.
Robbie doesn't take Rex to his Grandmother's house, but he does take Cat. This implies 2 things (1) That Robbie cares more for Cat than Rex and (2) He wanted to spend some uninterrupted time with Cat.
Tori the Zombie
Robbie and Cat were dancing together at the ending number, Finally Falling, in the musical together.
Jade Dumps Beck
Although Cat was absent for the episode, you can see that Robbie has a picture of the animal cat in his locker. This could be a hint from Dan that Cabbie may potentially become canon in future episodes.
Cat does not seem as angry as the others about Robbie spreading rumors about the group, although she doesn't like that they are taping her receiving a package from the Sky Store.
There were no rumors about Cat in the first Robarazzi video.
She does not go with the rest of the gang to crash Robarazzi.
The rumor about Cat's addiction to Sky Store was true, whilst the other rumors about the rest of the gang were lies.
Robbie makes a joke about Cat's hair color not being natural when Cat has specifically stated that it wasn't a natural color which could mean that Robbie didn't want to make up a rumor about Cat.
After Robbie yells at Cat, Cat seems as if she is about to start crying.
Survival of the Hottest
At the end of the episode, Robbie hugs Cat after she opens Beck's RV.
When Cat comes to sit down with Tori, Beck, and Robbie, she sits down next to Robbie. (When she sits down, she carefully moves Robbie's PearPad and he stares at Cat while she does.)

Wi-Fi in the Sky
Cat was going to tell Robbie the same joke she told the others, but he reminds her that she told him yesterday. Cat looks upset after he says this.
Since Cat told the joke to Robbie first this shows that she wanted to tell him before anyone else.
Cat doesn't seem to mind that Robbie is continuously trying to interrupt their video chat.
When Robbie enters the chat the first time, Cat is seen brushing her hair and not looking up. If you watch her you can see her nervously putting her hair in her mouth.
Cat's New Boyfriend
Robbie is not there when Cat first introduces her friends to Daniel, maybe because he didn't want to meet him, as he may possibly wish Cat were dating him.
Robbie tells Tori about the cheese fountain, and it causes Tori to see Cat kissing Daniel and ruin their romantic night. It's unclear if Robbie planned on leading Tori to the cheese fountain. It should be noted that before Robbie told Tori about the cheese fountain, he looked over at the cheese fountain and possibly saw Cat and Daniel making out by the fountain.
After Robbie told Tori about the cheese fountain, he looked back at the cheese fountain, possibly saw Cat and Daniel making out, looked at Tori again, and walk away sighing, putting his head down while shaking it.
Cat feels Robbie's foot when they are in the hospital.
Robbie calls Tori out for "playing smudgy face" with Cat's boyfriend.

Beck's Big Break
Cat is very worried about Robbie's sleeping problems, and tells him to go to the guidance counselor for help because he helped her with a lot her of emotional problems.
Out of all of Robbie's friends, Cat is the only one who shows real concern about Robbie's nightmares.
Cat wanted to know what Robbie was dreaming about and was upset that he wouldn't tell her.
When Cat wanted to know what Robbie's nightmares are about, Robbie says "None of your business!" possibly because he doesn't want her to worry, or maybe because he thought the nightmares were embarrassing and did not want her to see him in a negative way. After he said that, Cat gets all offensive and says, "Whats that supposed to mean? I'm trying to help!"
Cat seemed upset when Rex tells her that she is still a mess.
Lane said that Cat has been talking to him about Robbie's nightmares. This shows that she cares about him as a friend at least, in the fact that she refused his attempts to avoid counseling, and alerted Lane, for his well-being.
When Robbie is sleeping in class and the bell rings, all of their friends left. Cat was the only one who stayed behind and woke him up. Then she says in a concerned voice, "No sleep again last night?" Robbie says, "I can't stop having those disturbing nightmares." And Cat says, "Okay you gotta talk to Lane about this!" It seems as if she was gonna force him to go, which she did. She told Lane and Lane called him up.

After Robbie (and Rex) finishes singing, Cat cheers very loudly.
When Rex tells everyone to give his and Robbie's dates from North Ridge some "love", Cat applauded with a look of annoyance similar to the one she gave in The Birthweek Song when she almost left Robbie alone because Robbie's Mamaw insulted her. (This is probably because Cat is jealous of Rex and Robbie's dates.)
Even though the Northridge girls were technically Robbie's dates, Robbie makes Rex say that they were Rex's dates. This may be because that Robbie does not want Cat to think that he's not interested in her.
In the official music video for "Freak the Freak Out," Cat and Robbie are seen dancing together and having a good time.
When Haley and Tara win the competition, Robbie (through Rex) defends Cat by declaring that "Those scrounges (Hayley and Tara) can't sing!"
When the boys found out they were stuck with Trina, Robbie says he doesn't want to spend Saturday with Trina, showing that he HAS gotten over her.
When everyone found out that the only reason why Cat and Jade lost because one of the winners' father owned Karaoke Dokie, Robbie (through Rex) chanted "Fix!" and got the crowd to agree with him.
When Robbie tells the North Ridge Girls a joke, they doesn't get the punchline, in Wi-Fi in The Sky, Cat tells a joke and Tori, Andre, and Beck doesn't understand the punchline either. This means both of them aren't good at telling jokes and get along very well.
Cat asks about Robbie's date, possibly because she was jealous.

Cat is serious about taking Rex to the hospital, while the others are just kidding.
Cat seemed upset when Beck said that they were not taking Rex to the hospital.
When Jade suggested killing Rex, Cat seemed offended and even says "Jade" in a sad tone. Probably because she didn't want Robbie to be upset for losing Rex.
Cat doesn't seem to agree with killing Rex until Jade says it would be good for Robbie's mental health, proving that she cares about him enough to hurt him, for his own good.
When Cat says that Rex is not a puppet to Robbie, it could mean that she cares about Robbie's feelings.
Cat is the only one to understand Robbie and how he feels (especially since Rex is real to him).
The Diddly Bops
Further possible evidence of Cabbie compatibility is shown in this episode when Robbie almost obsessively tries to make their children song about broken glass. This strange behavior, taken together with the "Rex" phenomenon, may mean that Robbie and Cat are both equally insane.

Cat is the one that came up with Robbie's character for Sikowitz's exercise/sleepover.
When Robbie questions Cat's idea for his character, Cat looks down, giggles and says "Yeah I'm creative." As she walks to her seat.
When Robbie walks by Cat to announce Beck's character, Cat was still looking down and giggling while playing with her hair and slightly covering her face with her notepad.

When Robbie's "jelly legs" act up, he falls down and Cat seems both surprised and worried about what happened to him.
Cat and Robbie are the first two to break character, first Robbie then Cat.
In the program information for this episode, it said "Cat and Robbie sneak away from the party and confront their feelings for each other, inevitably engaging in a passionate kiss". Even though this didn't happen, this suggests that the producers were considering putting that in this episode, that Cat and Robbie 'engaging in a passionate kiss' is 'inevitable', and that they do have feelings for each other. (Some suspect that this will happen in season 3).
