I"m good with Mikan seeing just about anything, maybe izuku actually being...sorta cool for once... or something happy/warm w/his friends and family?

If you want Izuku could see something from Mikan's more villainous past... I was trying to think if there was anything lighter to see but they're few and far between, its mostly either full-on villain stuff or Monokuma telling them to murder each other or smth. sweats...
