Castle (Nathan Fillion) and Beckett's (Stana Katic) lives will be in grave danger in the upcoming season 8 finale of ABC's Castle.
ABC has released plot synopses for the final two episodes of Castle's current eighth season. As the end nears for Katic's run on the procedural, many fans are anxious to see how things will end for the detective.
Well, it wouldn't be Castle without a little bit of danger. This is the case for both episodes that will conclude this season, titled "Hell to Pay" and "Crossfire," respectively.
"When an axe-wielding, escaped psychiatric inmate drops dead in Castle's P.I. office, Castle and Beckett's investigation leads Castle to suspect the victim's death could be the work of the Antichrist," the synopsis for "Hell to Pay" reads.
While this may sound like an intense episode, the promo seems to cast things in a humorous light, with Beckett scaring Castle and smiling.
Guest cast for this episode includes Ronnie Steadman as Gabriel Shaw, Emanuel Loarca as Guard, Michael Chieffo as Dr. Brock Martin, Anne-Marie Johnson as Sondra Kramer and Matthew Borlenghi as Rollins.
Then, the season 8 finale will intensify the hunt for LokSat, which ends up putting both Castle and Beckett's lives in danger.
"With their best lead in hand, Castle and Beckett are ready to take on LokSat. But an unforeseen twist puts their case - and their lives - in jeopardy, on the season finale," the synopsis reads.
Guest cast includes Sunkrish Bala as Vikram Singh, Kristoffer Polaha as Caleb Brown and Jed Rees as Mr. Flynn.
Fans were shocked in April upon learning that Katic would not return to Castle in a hypothetical ninth season, nor would Tamala Jones as Lanie. The announcement was particularly surprising considering Katic has been Fillion's co-lead since the beginning of the series. It remains to be seen what showrunners Alexi Hawley and Terence Paul Winter may have in mind for a Castle without Beckett. The series has yet to be renewed.
Castle airs Mondays at 10 p.m. ET/PT on ABC.
