Death Wish - S8-E17
Continuity mistake: When Castle beings theorising that Genevieve might be a genie and that she wants him to be her new master, Beckett is holding a glass in both hands. In the following shot, she's holding it with just one hand.
Backstabber - S8-E18
Continuity mistake: When Wesley changes his statement after Hayley gives him a "swirly", his wet hair changes position between shots.
Lucky Stiff - S3-E14
Trivia: Firefly reference. When Beckett is talking to the drug dealer she tells him she likes to feel "shiny". "Shiny" was slang for 'really good' in Firefly.
Question: Before this episode, there was a Christmas episode "Secret Santa" and then there was "Significant Others" with Meredith showing up to take care of Alexis. In that episode, Beckett mentions choosing the movie Valentine's Day for a date night, causing her to lose a turn. In this episode, Castle and Beckett are celebrating their first Valentine's Day together. So, are they celebrating Valentine's Day twice? This wasn't too long after the Christmas episode and when Beckett made her movie choice, no snow was on the ground. Is this a mistake or is this really their first Valentine's Day together?
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.
