I do not own Doctor Who or Once Upon a Time. Only this story.
Chapter 1: The New World
Enchanted Forest
Snow White and Red Riding Hood walked through the snowy forest on a beautiful winter morning. Snow wore a white cloak to keep her warm and help camouflage her in case any of the Evil Queen's guards somehow found her. Red wore her signature red cloak. The cloak was enchanted to keep her from turning into a wolf during a full moon, not that she had anything to worry about in the daytime. Snow had taken refuge with Red for about a week now while she hid from Regina and her soldiers. They had just woken up and decided to take a stroll around the forest while Granny prepared breakfast for them. They kept walking until Red felt a tingling sensation all across her body.
"I don't feel so good." Red said to Snow.
Snow stepped back from Red because her friend was suddenly glowing with a bright purple aura.
"What's happening?" Snow asked.
"I'm not sure." Red said.
"Is it the wolf?" Snow asked.
"No." Red said. "That feels different than this."
Suddenly, Red's entire body and clothes started to glow even brighter. Snow turned away to cover her eyes. Red found that she had to close her own eyes because of how bright everything seemed. After a few moments, Red felt the tingling sensation go away. Then, she felt that it must be safe to open her eyes. However, when she opened them, Red found that she was in a completely different place and Snow White was nowhere to be found. Red was in a forest as before. Yet this forest was different. She was not on a cleared path, but in the middle of wild trees. The sky was black and she could see stars and a full moon. It was now night wherever she was and Red knew that she had to be extra cautious about her cloak, given that a full moon had risen.
Red walked through the forest, calling out Snow's name until she found something peculiar. In the middle of the forest, she saw a tall blue box that said "police" on it. She clearly wasn't in the Enchanted Forest anymore. She'd never seen anything like this before. Then it suddenly clicked in her head. This was the TARDIS. Snow White had told her stories about it and the strange man who lives inside. About a year ago, the Evil Queen sent three Sontaran assassins after Snow White. The Doctor and Amy Pond arrived to help Snow White defeat them. When the Doctor left, Snow was left with stories of her adventure with him. Naturally, Snow told Red about it, but left out some of the details. She didn't tell Red about the Sontarans for fear that she'd be frightened, but she said plenty about the Doctor. Red rushed up to the box and knocked on the door.
"Doctor!" Red shouted. "Doctor! Are you there!"
The door was locked and there was no reply. Red figured that he must be around somewhere if he wasn't physically in the TARDIS right now. She moved past the box in search of him and found what appeared to be fire in the distance. All she could make out was the orange glow. So she walked towards it. Eventually she reached the area and found that it was not a fire, but a series of candles set in houses. Red had wandered into a strange town, similar to her own in the enchanted forest. The women wore long dresses. Horses were the only mode of transportation aside from walking. Atop of a building, she found a white flag with a red cross on it, the symbol of the nation of England. Yet Red had never heard of England and had no idea where she had ended up or how she got here. She red a signed that said "Welcome to Boston". Evidently that was the name of the town she'd strolled into. Although perhaps Boston was another world. She felt lost in her own confusion. Suddenly, a man tapped her shoulder and she turned around to see him. He was tall and had brown, spiked up hair. He wore a blue suit underneath a brown overcoat. He wore red shoes, unlike any she'd ever seen before.
"Excuse me." The man said. "I'm sorry to bother you, but have you seen a woman named Donna? Red hair? Loud voice?"
"No." Red said. "Although I must confess I'm not from this place. Can you tell me where I am?"
"You're in Boston, Massachusetts." The man said. "This is one of England's colonies in the New World."
"England?" Red asked.
"Surely you've heard of England?" The man asked.
"No." Red said. "As I said I'm not from here."
"Do you know what year it is?" The man asked.
"No." Red said.
"It's 1692." The man said. "What's your name and where are you from?"
"My name is Red." She said. "I'm from the Enchanted Forest. I was walking with my friend and then suddenly I just started glowing and ended up here."
"I'm the Doctor." He said. "I've been to the Enchanted Forest once before with an old friend of mine."
"You're the Doctor!" Red shouted. "Oh thank goodness. I'm so happy your here. You can help me."
"How do you know me?" The Doctor asked.
"My friend is Snow White. She told me about how you saved her life back in the Enchanted Forest." Red said.
"Not yet I haven't." The Doctor said. "Snow White apparently didn't tell you that I'm a time traveler. Perhaps I will save her life, but for me that hasn't happened yet. So I'd appreciate if you didn't mention that anymore. If I had to guess based on your cloak, I'd say your little Red Riding Hood, just a bit older I presume."
"People call me Red." She replied. "I know about your TARDIS. I know you can take me back to my home. Will you?"
"Of course." The Doctor said. "But first I need to find my friend. We were walking through here and she started glowing purple and then she vanished. That matches your story exactly. If you came here, that probably means that she went to the Enchanted Forest."
"How did that happen?" Red asked.
"I'm not sure." The Doctor said. "Even I don't know everything."
"Who's your friend?" Red asked.
"Donna Noble." The Doctor replied.
