I'm jumping in to say I loved it too! Kept me on my toes the whole time. My head was spinning with whodunit's but never thought it was a party! I'm glad the captain couldn't come to the party because then would see Kate and Castle kiss. She still doesn't know about them, right?
I'll say it again (and I drive my husband crazy with it) but I just LOVE Ryan and Esposito. They are the best secondary cast members ever. Love their relationship with each other, love how they protect Kate when she needs it, love how they rib Castle all the time - almost like brothers. They're great.
and how funny is it that Martha "directed" the young actors.
Love love love
