It's Jon that finds her behind a bush, and he tries not to smile too noticeably at her soaked hair and dress. Arya, he suspects, had much and more to do with the worst of it. Who else could be so cruel to a surrendered foe but an unruly little sister?

He plucks the water gun from her fingers before she can greet him and presses a water balloon there instead. "These 'squirt-guns' are useless, we're not made for such things." He hefts his own water balloon as though to demonstrate their superiority, glancing over the bush they've camped behind. He does smile now, face red from running about and looking none too dry himself, feeling half a boy again (but not in the bad way that such thoughts usually come.) "With these, though..." He draws back, takes aim, and catches some poor combatant square in the back of the head, ducking again as though the bush is some solid place of safety like a well constructed snow-fort might be. "They're like snowballs. I've seen you win a snowball fight."
