As I watch the rebroadcast of the season I am struck by the amount of witty and enlightening  dialogue that is delivered so quickly that its content is lost or not able to be fully appreciated. There are often little gems of character development or info that give depth and meaning to what will surely be a developing relationship between Castle and Beckett; the writers have purposefully thrown it in the script but I fear time constraints or whatever is keeping much of it from making an impression without captions or even a 2nd or 3rd viewing.

Certainly Nathan's character is partially defined by his witty replies and quick, creative thinking and the go-go crime solving NYPD wouldn't hem and haw either. Still, I think involvement and interest in the show would benenfit from a bit of a slower delivery so some of the bon mots might shine.

Example : Becket''s comment in Ep.1 - ”is this a Mamet play” and Castle remembering that she reads plays. Good insight into another side of Kate – a creative and literary appreciation that would certainly tie them together. Then in Ep. 2 – their conversation about Castle nannying Alexis – his admission those were some of the best days of his life – Kate's dawning awareness of his complexity and admiration of who he really is – then his reversion to the playboy persona he likes to display by replying he was between marriages and thus it was a good time to meet moms in the park.

Both were fine writing, crafted to reveal a new layer but I didn't fully appreciate them until I went back and rewatched, listened more devotedly, or used captions. Just saying…love the show, love Nathan Fillion and Stana Katic and what they are doing with their characters - along with Sullivan and Quinn – and really would like to see it hang around a while.
