Maybe to make up for her less-than-perfect eye, Zuko has pretty sharp hearing, and even if she managed to shut her eyes, her ears are ringing from that bomb. She hasn't kept up with Ippo, but she's still closest to him of anyone in the group, and one of the first sounds that comes back to her is that unnerving growl he's making.

Zuko isn't really one to talk when it comes to letting her anger get the better of her in a fight, but she's at least come to realize that it's rarely done her any good to lose her head like that. Sometimes it can add power to attacks, but it can also make a person vulnerable. Ippo hasn't shown very good judgement on that front already.

"Hey!" Zuko shouts ahead to him. "You heard her, right? Keep up, but keep your distance." She can't see his face well enough to discern whether he's past listening to reason, but she can at least try to talk him down from doing anything else stupid until she catches up with him.
