"Yeah no that's really bad!!" he exclaims. "I mean blood drives are one thing, but someone could do some weird magic stuff against you with that! And all because you two refuse to accept stuff from me!"

It's because they're close friends that he can descend into scolding. On Midoriya it just looks like augmented worry with no bite. His hand is unconsciously moving the meat closer to her. This is one loophole he's been able to exploit, hiding behind the pretense of giving them food at a party where they must eat, or coming over with "just" some leftovers because he "made too much." It's rude for them to refuse, even if it begs the question why someone living alone would make an entire stockpot of stew. Todoroki, who eats out a lot because he can't cook, can't escape either.

It says something about Midoriya that's he's more disturbed by his friend trading her blood than skeletons. But, well, those bones are... dead! No more harm can come to them. Uraraka is a different story. Midoriya puts his bowl down, all thoughts of food scattered from his mind. He pulls out his Omni and begins rapidly typing a text to her on it.

"I might know some people who need odd jobs done. Texting you a list now."
