This Monday at 10/9c, in the Season 4 finale of ABC’s Castle, the murder of an Army veteran puts Kate (played by Stana Katic) on the trail of the man who shot her – meaning she’s perilously close to revisiting the murder of her mother. But Rick (Nathan Fillion) has privately vowed to steer his partner away from that conspiracy-laden powder keg, lest he lose her — forever.
Will Castle be forced to reveal the secret agenda by which he has been operating – and thus be punished by Beckett for a perceived betrayal? Could this finale serve up the biggest blow to the “Caskett” relationship… or, somehow, bring them closer than ever?
Circling back to the unsolved case of Johanna Beckett’s murder for the Season 4 finale is by design, says series creator Andrew W. Marlowe, since that story point always goes hand-in-hand with significant movement – sometimes for better, other times for worse — on the Rick/Kate front.
“Beckett is at her most raw when she’s dealing with her mother’s murder,” Marlowe tells TVLine. “That’s when she’s most emotionally vulnerable, even from the first time we touched this ground in Episode 10 of our first season, where Castle starts looking into [Johanna's] murder and causes their first rift. And at the end of Episode 213, ‘Sucker Punch,’ we have a very nice scene where Beckett accepts Castle’s presence – like, ‘I kind of want you around. I like you pulling my pigtails.’ Their emotional trajectory has always been intertwined [with the Johanna Beckett case].”
