With more souls escaping from hell, there are plenty of reasons to be worried for Sam (Jared Padalecki), Dean (Jensen Ackles), and Castiel (Misha Collins) on Supernatural. At the moment, however, we're more concerned about Rowena (Ruth Connell) who finds herself in a precarious situation this week. A trailer for Thursday's episode, airing at 8/7c on The CW, features the fire-haired witch asking a teary-eyed Sam if he'd let the world die just so she could live. That emotional exchange seems to allude to the prophecy that Sam will be the one to kill Rowena for good — but according to Ruth Connell, it may not go the way you think it will.

"With Supernatural, nothing is ever quite what it seems. It may well come as a surprise to all the characters, the situation that they find themselves in," Connell teased to TV Guide. "And for Rowena, the prophecies and magic are creatively important to her. So it's suggested here that what happens actually ties in with that, with how important she thinks magic is. [Magic is] her religion. It's her reason for being, so I think this episode will be quite satisfying in many ways for the fans."

The episode, titled "The Rupture," was directed by Charles Beeson, who also helmed Season 4's "The Rapture" and Season 6's "The French Mistake," among others. "The Rupture" promises to be a big one for the Winchesters, but especially for Sam, who Connell says will be dealing with quite a bit emotionally. And Rowena will play a major part in the events of the hour.

With so much going on, Supernatural hasn't had time to address the fallout from Jack's (Alexander Calvert) death at Chuck's (Rob Benedict) hand and how it affects others, like Rowena, who grew fond of him last season. Connell revealed that while this episode won't particularly address it, Rowena's reaction to Jack's untimely passing has weighed on her mind.

"Rowena really has a soft spot for Jack, and she helped heal him before. In this episode, he is still Belphegor, and I think I have my suspicions. We don't necessarily deal with it head on, what Rowena's reaction is to that, but for me, it's something I thought about a lot. I definitely want to take it into consideration that I would have just heard about this loss from the boys, probably," Connell said.

That we're able to discuss Rowena's affection for someone is quite a feat for the character who previously saw love as a weakness. Though she hasn't quite verbalized her feelings, it's clear that she has grown extremely fond of the Winchesters and especially Sam, with whom she shares a special bond.

"Rowena would never call it love, but I would," Connell said. "I think she knows Dean would pull the trigger if he had to on her, and she respects that. But with Sam, it's a kinship. When you both survive something similar, there's a special bond that happens. I don't know what Rowena would call it. I don't know if she would admit to it."

Rowena has come a long way since her Season 10 arrival as Crowley's delightfully loathsome mother. Though she's been able to connect with Sam on a deeper level, the same can't be said for her deceased son. Crowley sacrificed himself to help the Winchesters at the end of Season 12 and is presumably resting in the Big Empty with Jack. But as we've seen before, the dead don't often stay that way on Supernatural, so there's always the possibility that he can return. If Crowley somehow found himself face to face with Rowena again, Connell imagines that encounter would go terribly wrong.

"I think the real emotions would be there," Connell said. "I don't know how much either of them would like to show. I think there'd probably be miscommunication, and it would still end badly. There's so much water under the bridge. She might want him back, but she'd still want to pick at him, and he wouldn't do what she wanted him to do, and she still couldn't give him what he needs from her. But it would definitely be an interesting scene for sure."

Whether or not that encounter will happen remains to be seen. For now, Rowena is too busy trying to stop the end of the world. It's a work in progress.

Supernatural airs Thursdays at 8/7c on the CW.
