Harry grinned when the water started to ripple. Ron's face went pale and he tried to move away but stumbled and fell on the shore. Harry spun around to the other three and his grin grew impossibly wider when he saw that Dean had spun around on seamus, fully transformed.

He turned his head to catch Harry's eye and winked at him.
