* It's pretty clear that [[EvenbadMenLoveTheirMamas Jimmy loves his mom]], despite the tense interaction they have in the opening cinematic. When Gary [[YourMom insults her]] by saying she made her "living on her back", Jimmy goes [[BerserkButton berserk]].
* Despite treating [[TheWoobie Petey]] like crap for pretty much the entire game, Jimmy proves at the end that he truly does care for him: [[spoiler: Upon defeating Gary and untying Dr. Crabblesnitch, the latter tells the former that Petey should be the school's Head Boy (previously held by the now-expelled Gary), to which Jimmy agrees.]] Aww.
*** Add to that their final words to each other:
-->'''Jimmy:''' [[spoiler:Now, about that letter to my mother...]]
-->'''Crabblesnitch:''' [[spoiler:What letter?]]
