Castle Season 4, Episode 21, “Headhunters” Spoiler: Will Castle Go to the Dark Side?
Next week on CastleSeason 4, Episode 21: “Headhunters,” Nathan Fillion (Castle) will come face-to-face with an old crony when Firefly alum Adam Baldwin crops up to guest star as hardened gang unit cop Det. Ethan Slaughter.
But that’s hardly the only cool thing about next week’s ep.
With a last name like Slaughter’s, well, it’d be almost criminal if the guy wasn’t tough-as-nails. But according to Baldwin in a new interview with E!, the grossly-named detective might not be the only one engaging in a little rugged crime-solving. Um, say what?
Baldwin says Slaughter “definitely has unorthodox methods for crime solving” thanks to his crazy gang unit past, and while the Full Metal Jacket star says Beckett won’t necessarily approve of his unconventional tactics, he hints that the crime writer is actually rather intrigued by his character’s rule-bending shenanigans.
Unfortunately, that leaves Castle feeling a little torn. To be bad or not to be bad?
“He needs to observe but it's also strangely intoxicating for him too — to come along and see that other darker side,” says Baldwin.
Oh, boy! We can’t help but think that means that Castle probably dabbles in some "dark side" activities. We can only imagine how excited he’ll be — that is, until he finds himself scared silly. Bring on the little girl screams!
