In the Once Upon a Time two-hour season finale episode “Only You; An Untold Story,” Snow (Ginnifer Goodwin), David (Josh Dallas), Hook (Colin O’Donoghue) and Zelena (Rebecca Mader) find themselves at a mental hospital. They’ll need to find a way around a number of very disturbed individuals including the Groundsman (Hank Harris) and the Orderly (Arnold Pinnock). Both men are under the supervision of Warden Jacob.
Jacob the Warden is portrayed by Sam Witwer. He’s known for his roles on Being Human (Aidan Waite), Grimm (Max), The Walking Dead (Tank Soldier), Smallville (Davis Bloome), Dexter (Neil Perry), and Battlestar Galactica (Crashdown), among others. Or maybe you recognize Witwer’s voice from a Star Wars animated show or video game (Darth Maul, Starkiller). The two-hour finale of Once Upon a Time airs Sunday, May 15, beginning at 7pm on ABC.
