Water doesn't actually hurt me. [Okay, ocean water can in a sense, but he ain't sharing that information.] But I can't exactly do much if I'm at the bottom of a lake and unsurprisingly, I'm not a great swimmer. A ghost trying to get back out with me fighting them would just be a war of attrition and frustration and I can always win that war.

More than likely. Enough raw fire power and I've done it before. Once I know what's going on, I don't hesitate. [Even if he still has nightmares of fighting his father and what if Mei ever lost control of the Samadhi Fire again.]
