What a great episode last night! Definitely one of the best...even the mystery part kept me guessing! Beckett reading page 105 in the bathroom, and the little CIA agent who just disappeared... I especially love the relationship between Castle and his daughter though. As a single mom to a teenage son (opposite gender single parents), I see so many similarities to stuff we go through. Their relationship seems really true to life. Every episode there's some part where he's talking to his daughter (mostly when he's apologizing or explaining why he did something) where I just want to point to the screen and tell my son "Yeah, that. That's what I meant!"
