For a moment, Wrathion isn't certain how to react. But perhaps simple is best.

"I missed you, too. I thought about you, but...well. We've been over this." And really, he didn't want to rile Anduin up. He needs to sleep, not engage in another argument that was Wrathion's fault.

Nor is the dragon in a hurry to shift the priest away from him, either. He's well aware that remaining like this long term, falling asleep in this position won't do Anduin any favors, but for the moment, he's just going to...quietly accept this. Savor it.
