I don't want to take the whole "underwater tunnel that turns around on itself" thing too literally for distance. Though it does seem like it was far enough that normally, I could hold my breath that long. Maybe not long enough for a fight on top of the swim, though.

If the thing's outside the station, if someone or something could tug me down, I could probably still fight. If it's inside, then I'm out of luck. I won't fit shifted, and I'm useless in groundling form since I faded.
