What did Nathan Fillion say to Stana Katic?

While Nathan Fillion and Stana Katic have never publicly discussed their relationship on the set of Castle, sources previously disclosed that they usually don’t speak to each other on the set.

Nathan Fillion and Stana Katic reportedly went to couples therapy to get along better. Even though sources say that the co-stars didn’t get along, Fillion tweeted after Stana Katic was fired. In his own words:

“Castle has been one of the greatest joys of my creative life … Stana has been my partner all this time, and I thank her for creating the character of Beckett who will live on for all of us as one of the greatest police officers on television. I wish her well and have no doubt she will succeed in everything she pursues. She will be missed.”

Nathan Fillion is best known for playing the leading roles of Captain Malcolm “Mal” Reynolds on Firefly and its film continuation Serenity, and Richard Castle on Castle.
