Wrathion offers a blink in response, not quite certain how to respond, then turns a little more and reaches out with his other hand to tease Anduin's bangs aside.

"Then I am content," he offers. "Are you done?"

With his hair? Or is there more combing to be done...? He hasn't a mirror to hand to check, but he'll trust Anduin if he decides he is finished. Equally, if he thinks it requires more work he will submit. It wasn't, after all, an unpleasant experience to be tended to. One might even say it was... enjoyable.
