He quickly casts Healing Hands -while it wasn't a far drop from the dragon's neck to the ground, it's entirely possible for the Dunmer to have landed badly and been more injured than he looks- and once the spell's done its work he offers a hand getting up.

"I'm sorry you had to get caught up in that," he says, though it's an open question whether 'that' is referring to the battle or the strange encounter with the masked man.
