Since then, despite Beckett's then current relationship with another man, they begin spending increasing amounts of time together, with Castle even admitting he is jealous when Beckett agrees to help another writer with his book. In the final episode of Season 3, "Knockout", Castle finally admits his feelings to Beckett, who is apparently unconscious after being shot while delivering a eulogy at Roy Montgomery's funeral after Montgomery sacrificed himself to atone for his role in the death of Beckett's mother. She claims amnesia after she has recovered from the shooting, refusing the possibility of a relationship while her mother's real killer still walks free.
