Castle‘s season finale just got a lot more interesting.
Sources confirm to TVLine exclusively that Battlestar Galactica and Dollhouse vet Tahmoh Penikett has landed a potentially recurring gig on the ABC drama that kicks off in the emotional May 7 finale.
His role, not surprisingly, is shrouded in secrecy.
What we can tell you is that his character’s name is Cole Maddox and he’s cold, calculated and has a military background.
In other words, he’s bad news.
Penikett’s recent TV credits include guest stints on Haven, Fairly Legal and The Killing.
