Set at the end of Season 2

Castle had asked Kate out to the Hampton's for Memorial Day weekend however Kate already has plans with Demming.

Kate tells Demming they need to talk before they take off for the Memorial Day weekend. Kate gently lets Demming down but he is feeling raw and rejected.

All the gang are in the breakroom saying their goodbyes to Castle for the Summer as he heads off to the Hamptons to finish his latest novel. Everyone was in a great mood chilled out for a change.

Everyone, especially Kate is shocked when Castle walks out of the precinct with Gina for the summer. a short while later Castle heads back into the precinct mumbling to Gina that he's forgotten something.

Castle sensed that Beckett had something on her mind, his 'spidey' sense was tingling and he wanted to get to the bottom of it.

Yo bro! Espo called out when he spots Castle heading back down toward the breakroom. I thought you were long gone.

I just needed I mean I forgot to check something with Beckett before I headed off for the Summer.

Cool - I think she is still in the break-room.

Thanks Espo Castle sighs as he continues his search for Kate.

Castle makes his way to the breakroom, he stops when he hears a strange moaning sound emanating from the room. That's odd is sounds like...

Castle steps into the room and comes face to face with Demming. Kate has her back to Castle and Demming... is well ahhh noisily kissing Kate up and down. Demming notices Castle's entrance and just smirks at him and keeps going - that sight is not something Castle ever wanted to see.

Castle sprints from the break room straight to the closest bathroom and throws up. He stays until he has collected his thoughts.

Meanwhile Gina is not a woman who likes to wait around so 10 minutes after Castle said he'd be right back she jumped into the drivers side of the Ferrari and took off at high speed...

Three months later...
