"Do you know how bad salt water is for your hair?" he says, resigned to this. He can't let Cullen drown and honestly he's too tired to argue. "The oil would be fine. Your hair might not curl so violently with it."

He grabs his staff and gets up. "Now I can fish you out if you drown."

He is not going to allow his mind to think about Cullen bathing in front of him. It's only going to lead to trouble and Dorian is tired enough to do something about his emotions.
