kirishima asking bakugou why he was so adamant about paying him back and bakugou. just doesn't quite get altruism. so he's like "nobody does shit without expecting shit back" and kirishima’s like "the only thing I wanted 'back' was you"
remember when okamoto (bkg's va) was sad that bakugou wasn't with kirishima and kaminari in that one scene for s5 ed like you literally can hear him sulky pouting 😭
kirishima: i know i can be a lot sometimes so let me know if it feels like a chore hanging out with me and i’ll back off a bit!!
bakugou: i fucking love chores
Like he knows he can be a bit much but mocking people is just childish bully behavior. he'll side-eye them and give a Tch that would make bakugou proud. if he's really feeling feisty he'll pretend like he doesn't understand the mocking and make them feel REAL bad backpedaling
I headcanon that Kirishima will be his outgoing and rowdy self without second thought, with the compromise that he's chill when people tell him to quiet down. but if u MOCK him? his face goes flat so fast. like oh u think ur so funny? whatever man
the real reason they had to use disguises for kamino is because if kirishima tried to save bakugou in his normal ugly fit then bakugou would have preferred to perish
