“I can say that definitely it’s not the Brothers Grimm,” executive producer Edward Kitsis says. “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,” Kitsis says. “The finale will work much like that, in that the question of who these two are will be part of what the story is.”

“Sam and Hank play characters who play a pivotal role in the season finale,” EP Adam Horowitz adds. “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.”

A pivotal role in the finale, you say? I'm still going to go with the "Regina gets drugged by Jekyll/Hyde theory" xD
