ABC’s Once Upon a Time will shed light on two differently evil sisters during the back half of Season 5 — and to that end has cast tweenage Regina and Zelena.
For Once Upon a Time’s 100th episode, the series’ heroes and villains are going to hell. Literally. Waiting for them in the underworld, which resembles a twisted version of Storybrooke, is a new big bad played by Greg Germann.
