Yes, a key character really will die on the Castle season finale. Series creator Andrew Marlowe says it will be someone viewers have seen "many, many times before."
Among the other season-concluding tidbits Marlowe spilled to TV Line:
- The relationship between Beckett and Castle will play an "essential" role.
- Neither Gina nor Josh will appear.
- A "significant amount about the conspiracy" behind Beckett's mother's murder will be revealed.
- Fans should prepare for a cliffhanger and "a pretty explosive climax that has to do fundamentally with Beckett and Castle’s relationship."
The Castle season finale airs on May 16.
