"I didn't - maybe the me that you know came back, but ..." Izuku's feeling more and more frustrated, he didn't want to be fighting at all! This was the opposite of what he wanted! "You can't expect me to know all the stuff that future-me knows and change because of it when you haven't told me anything!"

And then Shoto stormed off, creating a little igloo for himself - okay that was really neat but - it meant he's hurt his feelings, too, and he's not even in a fight with him. Izuku finally shouted back at Katsuki.

"And now you've pissed Todoroki off and he's mad at both of us because we're both being jerks!" Izuku shot at him, angrily.
