[ Break probably could dodge this, at least now that he had his sight. He sees her pulling her arm back, and he reflexively shifts to avoid it, but he also stops. There doesn't seem to be any reason why, and so Undyne's fist crashes into his face and easily sends him tumbling back and spilling onto the ground. He may not be technically dying anymore, but physical strength and endurance was never really Break's strong suit anyways. And really, he's glad that he's already dead, or whatever this was, because I'm assuming you can't break ghost bones??? ugh whatever undyne punches him in the face and he has a bad time is the point

He gets up from the ground rather slowly as Undyne yells at him, though he's definitely gripping his face tenderly. It hurts, but even so, Break smiles, and surprisingly sharply. He looks up at Undyne, and unfortunately, this is just all of the emotions he's been keeping quiet bubbling up all at once. It's not even because Undyne punched him, since if he's honest, he knows he deserved it. ]

You think I don't know that?! I'm well aware that it was idiotic now, thank you, and at the time, I didn't know a damn thing about the demons or any of this nonsense!

[ He winces, since yelling definitely hurts his wounded face, but as those wounds start to trickle away into mist, he's briefly surprised. Even so, it's not enough for him to stop, and instead, he just starts to stand again. ]

I don't know what you've been thinking of me, but I'm not some hero that's trying to save everyone out of the goodness of my heart.
