Maybe it’s because I’m sleep deprived but the fact that shiro wakes up early to wear his armor and do push ups in his room is really funny to me. Like yeah, there’s the sad aspect where you can infer that Shiro can’t sleep due to nightmares and he only feels safe if he’s in armor but also. Dude wakes up at 3am. Can’t fall back asleep. Doesn’t want to leave his room because what if he runs into someone? What would he say? It’s 3am. He looks around but there’s literally nothing in this room except his bed and armor. He puts on the armor. He can’t go anywhere in his armor. That would just raise more questions. He looks in the bathroom mirror. He flexes. He considers. He goes back into his bedroom and starts doing jumping jacks.
