After Castle's series finale, the show's star Nathan Fillion sent off the show in the best possible way. The actor took to Twitter to thank the fans for all of their support over the past eight seasons. Not only was his tweet super sweet, but in true Rick Castle fashion, he even gave a figurative mic drop at the end. We are definitely going to miss seeing his character solve crimes alongside Kate Beckett (Stana Katic). See his post below!
Well. That’s it. Thank you, everyone. What an incredible journey.— Nathan Fillion (@NathanFillion) May 17, 2016
