A fun episode. Poor Ryan having to choke down that green glop. The rich sexual history of the victim (good grief!). I'm glad the wedding didn't take over the episode. Didn't care much for the dress Alexis picked out. Seemed a little old for her. Got a kick out of Castle's reaction when Kate asked if he'd expect to be given a detailed accounting of her sexual past. Hee. And what a cute surprise that Lanie's +1 was gay and that she ends up joining the wedding with Esposito.
And the very BEST PART: Kate is Castle's +1. 'Bout Time!
