The Doctor went off with Snow White, Prince Charming and the Queen to the Dark Forest. To see if they could find Glinda.

Charming stopped and bent down to pick up a white, bell-shaped flower in a clearing, which he gave to his wife. "For luck," he said.

Snow gasped as she took it, and then she looked at the Queen, who was staring at them. "What?" she asked.

"We're at the edge of the Dark Forest," the Queen began, "trying to find the one person who can stop our imminent doom and save the Doctor's grandchild - or your unborn child – and you two stop to smell the roses?"

"Snowbells," Snow corrected her.

"Oh, Regina, small, beautiful things are what life is all about for some people," the Doctor said.

"I don't care if they're bothered by dancing daffodils," the Queen said. "I need to destroy my sister. And so do you. If that babbling mad man sent us on a wild-goose chase, I swear …" She began walking again before she stopped and looked ahead. A door in the middle of nowhere. "What's that supposed to be?"

The Doctor walked forward and took out his sonic screwdriver before scanning the door. He read the readings. "It's a Spatio-temporal hyperlink," he read out.

"A what?" Charming asked.

The Doctor put his screwdriver back inside his coat pocket. "I didn't want to say 'magic door'."

"'Through the door, step inside. If pure of heart, then she won't hide'," Snow recited as she began to understand. "It's Rumple's riddle. It's Glinda." She approached the door and opened it before walking through and disappearing.

"Snow!" Charming called out after her, then sighed and followed her.

The Queen scoffed and approached the door herself. "A portal with a cheap cloaking spell?" she asked. But as she walked through, nothing happened. She didn't go to the place where both Snow and Charming were. Instead, she looked around, then marched back through the door again and shut it.

"Regina, I could have told you that wasn't going to work," the Doctor said, approaching the Queen. "In Rumple's riddle, he made it quite clear you have to be pure of heart."

She turned to him. "So, why didn't you go in after them?"

"My hearts are heavy with guilt with everything I have been through. That's not exactly being of a pure heart, is it?"

"I suppose not. So, what do we do?" "We wait. We wait for them to return."

And they did return. And Snow and Charming told the Doctor and the Queen what they had found out. And what they had decided that they must do. But the Queen wasn't happy with the news.

"Are you out of your minds?" she asked. "Even if I believed this Glinda, which I don't, to cast the Dark Curse, I'd have to destroy the heart of the thing I love most. Which, for me, is Henry."

"There has to be another way to enact it," Snow said.

"If there were, do you think I would have killed my father?"

"What about a magic bean?" Charming asked. "If we had one, we could open a portal. Or Jefferson's hat."

"There are no more portals," the Queen said. "Not for us. Not for anyone the curse brought back."

"And I'm afraid I haven't had any luck with the TARDIS," the Doctor said. "The void between worlds – between realms and universes – it's shut off from the TARDIS. Locked the TARDIS out from ever entering. Every realm ever existed, sealed off from each other forever. If there were a space-time rift that I could use to give the TARDIS an extra push, I would be able to use that to travel between realms, but I have not been able to find a suitable rift. Everything is closed off."

The Queen nodded. "When the Professor and I undid the first curse to escape Pan, to bring us here, it divided our realms. It placed a wall between them."

"So the Dark Curse is the only way," Charming mused.

"Haven't you been listening?" the Queen asked. "I can't cast it." "But someone else can."

Snow looked up at her husband. "Who?"

"You." He knelt in front of his wife. "It's the only way. You can use my heart to cast the curse. We have to think of our people."

Snow shook her head. "No. Our child needs you. I need you. We'll find another way. We always find another way," Snow said, but Charming just sighed.
