Just like us, AOL TV Squad editor Isabelle Carreau hearts Nathan Fillion. When asked which TV celeb she'd follow to any project, she responded, "I would follow Nathan Fillion anywhere. He can play it all, from an ass-kicking commander of a ship in Firefly to a charming and full-of-himself writer in Castle. Just following him on Twitter makes my day as he is engaged with his fanbase and his Tweets are fun. Did I mention he is charming?"
