It isn't often that we get to see everyone from Castle dressed up and enjoying an evening together. They certainly look to be having a wonderful night.
The best part about the "Reckoning" was that for the first time in the series, a Castle two-parter ended with Rick and Kate getting through it together.
One of the best things about "Private Eye Caramba!" was the Caskett role play. Kate Beckett was "just a girl looking for a private dick." Looks like she found one.
