allison and derek trying to have a serious conversation at a pool, their barefeet in the water.
the conversation turning into an argument and that argument leading to allison shoving derek into the pool.
the tension suddenly lifting as allison bursts out laughing because derek’s face is priceless.
derek trying to pull her into the pool in revenge but her having too good a grip on the pool’s side.
allison and derek suddenly being a breath apart, acutely aware of of his hands on her body and the distance between their lips.
that tension building until, on an impulse, allison leans forward.
derek using the moment’s distraction, the lessened grip on the side of the pool, to take his revenge at last.
allison coming up out of the water gasping as derek laughs.
allison flicking water his way, furious but laughing herself, and the childish fight leads to derek pulling her close.
allison kissing derek first and thinking he tastes a little like chlorine and desire.
