In order to save Emma (Jennifer Morrison) from the Darkness, Merlin (Elliott Knight) must unite the Dark One dagger with Excalibur, which is why he enlists the group to steal the broken sword from Arthur’s (Liam Garrigan) castle. “We’re a bit naïve,” Ginnifer Goodwin jokes of bringing the Wicked Witch along on such a vital mission. “Haven’t we been here before? The audience will be a half-step ahead of our gang in terms of what could befall them in teaming up with Zelena. Does anybody really think that’s a good idea?”

No, but they don’t have a choice. “There’s a reason,” Sean Maguire says of why they

bring Zelena along. “We don’t want to, but there’s something she can do. There’s an advantage to using her. We question whether or not we can use her and if it’s going to backfire. None of us trust her. We know she’s evil, but at the same time, we’re trying to collectively find a solution to the problems that we’re currently facing and they need drastic resolutions quickly.” Suffice it to say, working with she-who-was-previously-green won’t go as planned.

Meanwhile, Emma and Merlin will go on a quest for the magical means to unite the sword with the dagger, putting her in the vicinity of the original Dark One. “She starts to realize how dire the circumstances are,” Morrison says. “She felt much more in control until that point. Now she’s realizing what she’s up against, how powerful that Darkness really is within her. It makes her realize that as powerful as she is, and as in control as she is in certain ways, there are things that feel much bigger than her still. She definitely has an uphill battle.”
