ADA Toni Gonzalez: You want the DA's office to do what?
Captain Victoria Gates: All we're asking for is a delay until we can sort all this out.
ADA Toni Gonzalez: No. What you're asking for is preferential treatment for a murder suspect. You want to sort this out, you sort it out after he's arraigned.
Kate Beckett: No, I don't think you understand. There's not gonna be an "after".
ADA Toni Gonzalez: If it's his safety you're concerned about, we're prepared to put him in protective custody.
Kate Beckett: Do you have any idea who you're dealing with? Do you even know what Jerry Tyson has proven himself ...

Just when you thought it couldn't get any better
30 October 2012 | by See all my reviews

Aside from the great character development of this series, this time I have to hand it to John Terlesky and his directing. This episode began rather slowly and I found myself thinking, for the first time, the series was really starting to get old and predictable. Then it happened, Great directing, acting, and story telling that keeps you plastered to the tube! This has got to be one of the very best episodes. I loved the series Firefly and followed Nathan Fillion to Castle, albeit 2 years after it premiered. Obviously, I wasn't expecting that same magic. I am happy to say that this series really invests in the characters. In turn, you can't help but find yourself investing in them too. If you are new to Castle, I highly recommend that you start watching from the beginning and catch up. You will not be disappointed!
