Hoisting both Jasper and Herbert above his head, his legs dangling over the rising water, Steven screams a little when the lightning surges. He's technically above water level with them, but with the way it's moving, it's hard to guarantee they stay that way.

His wings flap and his legs kick as hard as they can, trying to gain more momentum upwards. Sadly, his wings are less willing to carry this weight than his floating powers are, and his floating powers require something to jump off of.
