It's Time Travel, Dearie.

Rose

Rose sits at Granny's with Belle, who tells her every story book character is here. Rose gasps. "Snow White? Are you serious?" Belle giggles and nods. "And Granny? Ruby is her grand daughter."
Rose laughs and starts eating.
"So what were you doing? 28 years right? Did you own a shop, did you work with Rumple?"
Rose stops eating and looks at Belle who had gone quiet. Rose instantly regrets mentioning it.
"I'm sorry- you don't have to tell me if you don't want to-"
"I was locked up in an asylum for 28 years. Before that- after I left Rumple's castle, Regina captured me. Apparently Rumple went more insane, Regina had told him I died."
Rose reaches across the table and squeezes Belle's hand.
"I'm so sorry."
Belle smiles.
"It's okay now though. Rumple and I- I'm the only one left who cares for him. His son, died a few months ago."
"Oh my. I'm so sorry."
Belle nods and looks down.
Rose looks down too, suddenly not hungry anymore.
"Rose!"
Rose lifts her head and looks up at the Doctor who comes running in. "No time to explain! Bring Belle. Let's go!"
Belle quickly pays for their meal and all three run out.
