Nathan Fillion once explored the differences between his characters in ‘Castle’ and ‘The Rookie’, which were two of his most famous roles.

Of course he does. Nathan Fillion's horrible treatment and hate of Stana Katic on Castle ruined the last two seasons since he refused to do scenes with her. :rolleyes: :mad:

The Rookie's original female lead quit after just one season, I wouldn't be surprised if he treated her like dirt as well.

I agree. I loved Castle. He ruined it thinking their could be a castle without Beckett.
