Neville Longbottom

[Yeah, that one's a doozy. Cold water is freaking cold and damnit, we're going to get rid of it.] I'd like to think of it as advice from someone more experienced in these things. [Sort of joking and smirking in response. Warm atmosphere for the stopping of the cold! Harry will probably find this weird upon reflection, but the saving-people-thing has kicked in and he's taking charge like a Gryffindor. Hopefully Arumat is used to that popping sound by now.] Don't worry about it. Change out of those clothes before the cold sinks in, then get under the blanket.
