 * He gets reservations for Mike and Celia at Harryhausen's.
 * He covers for Mike when he forgets his paperwork so he could go on his date with Celia.
 * Unlike Mike, Sulley refuses to abandon Boo or just get her through another door instead of her original door, and attempts to look for her when she's lost.
 * He is horrified when he believes that Boo was killed in the garbage disposal, and upon seeing her alive, he hugs Boo in relief.
 * When he learned that Randall placed Boo's door on the scare floor as Mike revealed from his deal with Randall, he refused to put her in there well-knowing Randall's true nature and plot and persuaded Mike to not do so.

 * He feels remorse for accidentally scaring Boo and starts to realize the trauma monsters inflict upon children with scaring.
 * He apologizes to Mike for getting both of them stranded in the human world.
 * He protects Boo from Randall and Waternoose and saves her from being experimented on with the Scream Extractor.
 * He tells Mike that he's happy his friend returned to help.
 * He attempts to reason with Waternoose and convince him there's a better way to keep Monsters Inc. operating.
