In September and October, Stana tweeted about her time on and off set, a few pictures and more silly random tweets. Stana also replied to several fans and posted several songs.
When a fan sent a picture of a handcuff wedding ring for Castle and Beckett, Stana replied “whoa whoa whoa!!!!They just started dating.Mamma mia.” She also provided a little tease before the season started.
The show is very cheeky this season. In fact, it has its tongue placed firmly in its cheek. #castlelovesbeckett

Our favorite female tv detective also posted about a real life detective. "Fun fact: Kate Warne (1833- January 28, 1868) was the first female detective in the United States."
Finally a few silly tweets from Stana, as well as a video of Stana using her superpowers on the set while filming “Probable Cause.”
Note to self (and every1 else): getting in a car w a sombrero is tough.Happy Day of the Dead.
