It's Time Travel, Dearie.

Belle

"Where exactly are we going?" She asks, after hanging up with Rumple, telling him where she was going.
"To the TARDIS!" The Doctor shouts.
"Is he always like this?" Belle whispers to Rose who laughs and nods.
"The Doctor opens the door and walks in.
"Oh wow.... Rumple would love this! Is this, bigger on the inside?"
Rose shoots the Doctor a look and grins.
"So why are we here?" Belle asks.
"I found something. A heavy supply of magic."
"Magic? Really?" Rose asks.
"Yes really. Rose- your universe is small." Rose huffs.
"Yes I know."
Belle looks at the Doctor.
"Storybrooke has been here for 28 years- but it was under a curse. It was recently released."
The Doctor nods. "The TARDIS has just picked it up. And found its way here. That's why we landed here Rose! Magic jackpot!"
Rose laughs. "Bloody brilliant!"
Belle raises her eyebrow, but says nothing.
"Wait so this is a time machine?" She asks. The Doctor nods.
"Can it take us back to our world?"
The Doctor frowns. "Sadly no. It can't travel to parallel worlds."
"But our land isn't parallel."
"It's timey wimey." The Doctor flicks his finger.
"Belle sighs and nods.
"It was worth a shot anyway."
"We can leave now, Rose!"
"But we only just got here!" Rose says, crossing her arms. "Can't we stay here just for a bit longer?"
"But Roseeeee-"
Rose looks at the Doctor with such a look Belle laughed.
"Come on Doctor. I could show you around."

Belle says good night to the Doctor and Rose and walks back to Rumple's shop.
She walks in the back and sees him spinning. She sat down next to him and kissed his cheek.
"Hey sweetheart."
Belle smiles and sighs, closing her eyes.
"The Doctor and Rose seem like such nice people." Belle says.
"I don't trust them." Rumple says, continuing to spin.
Belle rolls her eyes. "You don't trust anyone, Rumple."
"You are wrong there, dearie." Rumple looks at her. "I trust you."
Belle blushes and kisses him.
"Love you." She whispers, laying her head against his shoulder. The spinning stops and he puts his arm around her.
