It's been awhile since Peter's been swimming-the one mission not withstanding but since that was like a month ago it still counts as having been awhile. So, now that there's not really a threat of being attacked, he's going to just enjoy the chance while he can.

He notices Buttercup practicing swimming and feels a small swell of pride and as he moves into the water.

"Not bad." He compliments. Now if only someone could teach that Misa girl that swimming is a good skill to have.
