Monsters University Head Canons *may contain spoilers*

*Alright, so I started this a few months ago and said I would publish it the night before the movie comes out, but now, I've already seen the movie and have decided to confirm or deny these. Reminder, there will be spoilers!*

I won't call these predictions because chances are, plenty of them won't be in the film. I just thought I'd take my guesses and see how close the film gets.

I'm gonna continue updating this with conformations, denials, and additions, and put it up the night before the movie comes out.

- Randall and Mike are best friends, as they are both "nerds".
  - Update: This is more than likely seeming true.
CONFIRMED

- Celia and Sulley are dating; and Celia wouldn't give a second thought about dating Mike.
  - Update: from what it seems, Celia won't be in the movie.
DENIED mostly. A picture of Celia is seen near the end, but that's it.

- Waternoose and Roz work at the university, Waternoose perhaps as a long-time alumn and of presitgious honor, and Roz perhaps as a lunch lady or custodian. Another thought is that Waternoose visits from MI to give the students a talk about the company.
   - Update: Waternoose is no longer on the Wikipedia, so I doubt he'll be in it.
DENIED mostly. Like Celia, a picture of him is seen near the end, but that's all. Roz makes a brief appearance near the end.

- With regard to the "You've been jealous of my good looks since the fourth grade, pal" line in the first film, perhaps they knew each other somewhat in the fourth grade but didn't remember it when they went to college; it only occurred to them once they became friends.
   - Update: This is more of a head canon, as Pixar says they'll probably just ignore it.
NEITHER CONFIRMED NOR DENIED. Just ignored, as Pixar planned to.

- While practicing, the scaring majors will try and scare Boo's mom.
   - Update: This is really just wishful thinking.
DENIED.

- Most of the other scaring majors in their fraternity weren't scary enough to make the cut, and thus we didn't see them in Monsters, Inc.
NEITHER CONFIRMED NOR DENIED. In the credits, it seems that the OKs became scarers, and yet we don't see them in the other movie. Also, some other students like the RORs ended up working at different scare companies.

- Don Carlton was one of the first monsters in his fraternity and hasn't been successful with the rest of his life and thus has stayed with them. He might be the uncle of Squishy, or at least act like one.
PARTIALLY CONFIRMED, PARTIALLY DENIED. We're not sure if he was one of the first brothers, he seems to have just gone to them once he went back to college. He ends up being Squishy's stepdad.

- Fungus isn't popular, but doesn't start out as a friend of Randall's, either. Maybe he makes fun of him.
DENIED. No Fungus in the film, sadly.

- Sulley gets extremely nervous when he gets his job at MI, and thus, starts working out regularly as opposed to never doing so as he used to.
IMPLIED CONFIRMATION. It seems as though Sulley didn't work out as much because he thought he could just wing scaring and be good at it. Once he understood it takes more than that and got to the big leagues, he knew better.
