Flowers for Your Grave - S1-E1

Trivia: After learning a murdered television host was planning on changing his show-ending signature line, Castle suggests to Beckett that they should have a signature line of their own, and suggests "A whole new chapter in crime solving." This is actually the tag line on the season 1 DVD set. The other line Castle suggests, "She's armed, he's dangerous", became the tag line on the season 2 DVD set.

Trivia: Castle's Halloween costume is of Malcolm Reynolds, played by Nathan Fillion in the short-lived TV show "Firefly." Alexis asks him: "Didn't you wear that like five years ago?" Serenity, the film based on Firefly, was released 5 years before this episode aired.
