"Why the bloody hell is this so cold!" England shivers, his gangly arms claw at the tiles, trying to drag himself back up.
This was the reason I didn't use the stairs. Its a lot hard to leave when you have to exert your own strength to do it.

"C'mon, England, you promised."

He doesn't budge. His lips for twist into a disgusted scowl, as if the very idea of swimming makes his skin crawl. It probably does though.

I grab his arm, dragging him deeper into the waters until he's waist deep.
