Like Father, Like Daughter - S6-E7
Beckett: Castle, I am not getting married in space.
Castle: Why not? We could be the first. Commercial space flight is only a couple of years away. And you said you wanted it to be special.
Beckett: [sarcastic] Yes, because when I was a little girl, imagining my wedding day being stuck in a small tin can with a thousand tons of rocket fuel strapped to my ass was exactly what I had in mind.
Answer: The networks are now having winter breaks. A mid season end of new episodes, when they come back after the new year, it picks up as if several months have gone by. Beckett suggested Valentine's Day as a "chick flick" to watch as she is moved in. Also some episodes are not scheduled to air in order.
