I think I should be able to. [That is, if it's only the arm that would break. The fact that it's working up old injuries makes him worry for his legs...but his right arm had always been the worse off.]

I haven't actually walked far enough to test if my arm will actually break, it just feels very similar to when I broke it. [Izuku is looking at the arm in question, flexing his fingers.] It's possible that the break would repair if I came back, but I want to get more information before I test something that risky out. The pain goes away when I come back, but-- [He holds out his hand, the pinky purple and bruised] --my finger still looks like this, so at least some physical repercussions remain.
