There is a few people that thought they were a couple. あなた see Alex Conrad needed Castle's "Permission" to call Beckett. Will Sorenson (Beckett's Ex Boyfriend) He knew that 城 liked her. The Red head woman who was a profiler thought that they were together. Castle's Ex girlfriend who is know married 発言しました to Beckett "He's All Yours" The FBI guy who helped them when there was a bomb and when they were in the freezer. He thought that they were a couple. あなた have everyone at the precinct thinking that 城 and Beckett should be together! :D Also Josh noticed because he was protective of Kate when 城 was around. あなた had Royce (Beckett's police trainer) he knew that they had something real in the note that he wrote her he told her! There あなた have it there is sooo many people that thought they were a couple! :)
