"What if saving this world means that Azeroth is saved as well?" Whether or not their world is destroyed or not, clearly it's imperiled somehow if the two of them are there. That is what Wrathion is taking from all of this, in any case. He does not particularly care about Horos, save for how what happens to it affects Azeroth.

Saving their home. In that, he and Anduin are aligned. The dragon will cling to that. Even the irrational anger releases slowly from him at that thought.

"Anduin...what if we're being blocked from sensing Azeroth? I'm sure you've heard that the Regent is incredibly powerful..."

After all, if Wrathion could do such a thing, with the added benefit of fomenting despair which also gave him strength? He would. And this is what he's heard of the Regent, so why wouldn't they? It would cost so little to them, and benefit them greatly in both power and in other means.

And the Young Lion is...not doing well. Not that Wrathion had been, either, but he has things to...distract himself with, now. The wheel of his thoughts has been given something to grind. No such boon for Anduin, however. So, as awkward as he knows this might be, Wrathion moves, scooting towards Anduin to reach for him and sling an arm over the young king's shoulders. He might never believe it, but Wrathion is...attempting, at least, to give Anduin a hug.

Not that he'd blame the human for shoving him away.
