Nathan Fillion & Adam Baldwin together again on Castle [Sneak Peek]

Nathan Fillion will be reunited with his Firefly co-star Adam Baldwin (formerly the man they call Jayne) on Castle this Monday. Baldwin is set to guest star as tough guy Ethan Slaughter, a detective from the NYPD gang unit, opposite Fillion’s Rick Castle.

Read on for three sneak peeks and the episode description for “Headhunters” .

Updated: Now with more Jayne (three more clips)

With tensions rising between Castle and Beckett, Castle finds himself a new partner — Detective Ethan Slaughter (guest star Adam Baldwin, “Firefly”), a tough and colorful cop from the city’s gang unit. But Castle gets more than he bargained for when Slaughter shows him a grittier side of police work that puts Castle in the line of fire like never before

I look forward to seeing the tensions between Mal and Jayne…err.. Castle and Detective Slaughter and see how this new arrangement plays out with Beckett, Ryan and Esposito.
