Anduin lets out a humourless huff, lowering his eyes again.

"A lesson learned," he repeats, "for both of us, I think."

An unpleasant one for Anduin, but he has borne it. He frowns at the ground, thinking, then lift his eyes back up to Wrathion.

"I'd thought we were friends," he says simply.

Yet Wrathion's behaviour had not been the behaviour of a friend. Knocking Anduin out, leaving him behind, abandoning him for years. That is not what friends do, whatever way you look at it.
