That's probably true... Leo doesn't spend a lot of time flying like Donnie does, but just from jumping across rooftops he knows that water drops hitting your face at high speeds is often unpleasant.

Donnie gets up and Leo follows him. It's a little easier when he doesn't have any extra weight. He's not even wearing clothing beyond his normal gear, so he doesn't have any fabric weighed down with water.

"Yeah, got it."

He slides behind Donnie, hits the release, and...

"Pizza Supreme this thing is heavy!"

No wonder he just collapsed once they got out here.
