Beckett: Are you getting mail here now?
Castle: Only when I don't want my daughter to see it. (opens the envelope to show 2 tickets for Taylor Swift concert) Laa...
Beckett: You're a Taylor Swift fan?
Castle: They are for Alexis. Cost me an arm and a leg, but Alexis will be thrilled. Apparently she and Ash have a song.
Beckett: Yeah, well we have a song as well.
Castle: We do?
Beckett: Uhuh. "You talk too much" by Clarence Carter.
