Holy shit, that was a lot easier than he was expecting. Lambert doesn't quite do anything like whoop out loud, but he does watch with interest as the bubbles slowly stop and the lake returns to its placid calm, mentally counting the seconds passing by. Of course, he's not at all worried about the vampire dying from a little asphyxiation, but he is curious how long he's going to stay down there...

When he hits around the five minute mark, if nothing further happens, Lambert shrugs, stands, and dusts his hands off on his pants. Well, he was wasn't much of a conversationalist anyway!
