Happily ever after

My favorite couple from Disney is not really a "couple" perse but more best friends. They are Sully and Boo from Monsters Inc. Now, we know that Waternoose made Sully destroy Boo's door but Mikey put it back together for him. At the end of the movie we see Sully go into Boo's room and then the screen cuts to the credits. I think that what happened was that Sully went in and gave Mike instructions for after he shuts the door. I came up with the theory that Sully had Mike shred the door so that he and Boo could be together forever. I like to think that Sully would leave behind his best friend, Mikey, to be with the little girl that he absolutely loves. Of course Mikey loved her too but one had to stay behind because no one would shred the door for them if they went through. So Sully asked Mike to do the unthinkable and he did.
