Leaning back slightly more was about the extent that Todoroki could muster before simply staring at Bakugo. What was he supposed to do now? Was this some sort of strange side effect? Would it wear off and Bakugo suddenly go back to normal later and want to fight or explode his room. He knew the other boy couldn't actually hurt him, not easily, at least. Same as him setting fire to Bakugo would be an inconvenience probably at most...and worse for everyone else around.
He just let himself move to the bed, and even if it wasn't the type of bed he wanted, whatever he actually did want right then, it seemed a great option to rest. His eyes were starting to burn. Maybe it was the light, or just the fact that he'd spent all night awake and alert and was now suddenly full and maybe even more confused than he'd ever been. "You're quite bossy for someone who looks like they need a nap, too."
Frowning, he did settle, watching Bakugo move with more ease than he probably should have been able to. There had to be something to that, but Todoroki's brain wasn't exactly offering up anything at the moment. He just closed his eyes, partly for himself, partly because he thought Bakugo would just be annoyed by him laying there and staring. Though, Bakugo's calm movements were strange, even if Todoroki had watched him be calm plenty of times in the middle of a lesson.
In the end, he couldn't ignore the implications, or maybe he was just imagining it. He raised a brow, wondering if he should ask. Though, it could probably be assumed that Bakugo was simply thinking that if Todoroki woke up hungry, he could very easily hurt someone. It wasn't anything more than that. He waited, following Bakugo's movements for a moment before taking on a look of surprise, his eyes widening slightly for a moment before reaching to take hold of Bakugo's wrist before he could pull back.
His mouth opened, like he thought to say something, but the words never quite made it. What would he say? Stay? Why? So, he could simply attack the other boy again? No. Maybe something else. Still, no. He looked away, thinking, trying not to let the silence stretch too long before looking up again, suddenly feeling something bordering on exhaustion. "My belt's by the door. It should have everything you'd need to patch yourself up. Take it." The words felt a bit dead, even to him. He exhaled, letting go and shifting to cover himself again. "I'll try not to go anywhere when I wake up."
