[She does not have to regret, wait till she meets his roommate, who he has gotten in literal fights with and his still fond of. Or his mentor who is as likely to greet him with a headbutt as a pat on the shoulder. He apparently is drawn to people who threaten him with physical violence. Hey! He's got a groovy scar she can see someday from where his friend totally almost killed him but he was saved by surgery and saved being paralyzed by the magic of friendship (Or more an enemy turned ally with timelines being wonked out like a mofo.).

He follows her gesture and starts walking, he is quick enough on his feet that keeping some distance does not worry him, he can still catch her if that exhaustion becomes too much. Till then she is met with a smile and relaxed young man who will not be ruffled by her threats.]

Yamamoto, it's nice to meet you Azula. I'd say welcome but it takes some getting used to. At least there aren't any kraken right now or a hug-a-thon.

[Cause both of those were fun. Well Hug-A-thon kind of was but for now he is just keeping an eye, making sure not to get too close so she does not get jumpy. That's another thing he is used to, he is so openly comfortable with friendly touching but some people aren't and he has a tendency to make them uncomfortable without meaning to once he knows a person.]
