The Rookie to Stage Another Castle Reunion This Season

at .

If you're a fan of ABC's The Rookie, then there's a good chance you were also a fan of Castle, another procedural which also starred Nathan Fillion. 

The sophomore drama series recently staged a Castle reunion, and the series will be doing so once again. 

TV Line is reporting that Annie Wersching has been locked in to appear in an upcoming episode as Rosalind Dyer, a serial killer on death row who finds herself getting a little too close to Fillion's John Nolan.

If you watch Castle online, you will recall Wersching from that series as Kelly Nieman, a prison doctor/plastic surgeon who grew obsessed with Jerry Tyson. 

Jerry carried out a string of heinous slayings throughout his turn on the series, and Kelly later became his accomplice and love interest.

It was a gripping plot, but it remains to be seen what wicked things Wersching's new character will get up to on The Rookie Season 2

If you watch The Rookie online, you know that Nolan has found himself in some crazy situations, but somehow, this serial killer arc certainly sounds like a scary one for him.

The Rookie already played host to a Castle reunion earlier this month, with Castle cast members Seamus Dever and Jon Huertas appearing in an episode as part of ABC's "Casts From the Past" week. 

Wersching is no stranger to the small screen. She is currently a series regular on Marvel's Runaways and has also appeared on the likes of The Vampire Diaries, Timeless, 24, and General Hospital.
