‘Once Upon a Time’ season 5 finale: Show bosses on mystery castings, season 6 setup

For the past couple of weeks now, there has been some sort of mystery surrounding a pair of castings in relation to “Once Upon a Time.” Specifically we’re talking about Sam Witwer and Hank Harris playing the head of a mental institution and also a patient who is frequently tormented there. There have not been many reports out there as to who they will be playing but executive producer Edward Kitsis did shoot down one fan theory today to Entertainment Weekly: The two are not the Brothers Grimm.

Instead, he tells the site that the intention here is to get to know these two characters first before eventually revealing their true past, something that he explains while citing a certain fan favorite played by Jamie Dornan:

“What’s fun about those two characters is very similar to season 1, when we didn’t know who Graham was, and we were guessing sometimes what character they are … The finale will work much like that, in that the question of who these two are will be part of what the story is.”

Meanwhile, fellow showrunner Adam Horowitz made it clear that we are actually going to see these two help to set up a story in the sixth season, and we’re immediately curious as to see if they are a major part of that:

“Sam and Hank play characters who play a pivotal role in the season finale. Where they’re from, who they are, and what they’re doing does tee up an element of what we’re doing for season 6. It’s more like opening a door, rather than introducing the whole of what season 6 will be. Hopefully we’re giving you a little taste of what’s to come.”

There is a little bit of story to go until we reach the big season finale, so with that in mind, let’s stress one thing above all else: Patience.
