The encounter with the Classroom Admirer, in the doorway of the Classroom after class; do they ever remember what they wanted to say?
Completely unrelated; if you decide not to go the trash human route with the 'Rich Kid' all the guys from his hall who previously seemed decent enough do a heel turn. Do any of them not do that? Like maybe if you have gotten their friendship up to actual 'friends' rather than just acquaintances?
Related to THAT; While I love that you now know what major an NPC has after interacting with them enough, will it ever be possible to add what their Residence hall is (even if it isn't yours) and who their Roommate is (again, once you have interacted with them enough)?
