Shoto has a hard time believing that someone 'magicked' away their quirks, especially and specifically because he's seen Bakugo with his just now. They're not gone, they're something else. Then again... why would Bakugo make that up? It's frustrating to think about and he doesn't want to think about it for now.

"No one..." he sighs heavily, he had considered maybe it could have been a quirk itself making them think that, but why would they use that as the background for it? They wouldn't. "

His eyes are down more than on Bakugo at the moment until he asks him and in a sincere way that he knows Bakugo isn't messing around. His eyes tick to the scars, then mismatched back up at crimson. "Yes. I know how you got them, and yes." it's just 'yes', but he feels the clarification is necessary.
