ElevenXRose- This is an Alternate Universe trailer involving the Dream Lord, the Eleventh Doctor, and Rose Tyler. I left the ending open so you can image how it ends for yourself.
Here's the storyline if you couldn't already tell from the video:
"So the Doctor, Amy, and Rory are confronted by the Dream Lord who tells them they have to pick which world is real. In the village world the Doctor finds Rose. They have to face a danger in both worlds. Rose and the Doctor are extremely happy to have found each other (there's no Tenth Doctor Duplicate in this reality, since it's basically the Eleventh Doctor's fantasy). The Doctor is unsure what to do since he wants to stay with Rose but isn't sure if it's real or not. Rose is upset because she believes her reality is false and the Doctor is dieing in the real world. She receives a call from the Dream Lord telling her that if she picks a world for the Doctor she can save him. She has a vision about Bad Wolf and realizes that she can save the Doctor... though it might take her life in the process."
Quotes:
"Well. If you're the Time Lord let's call me the Dream Lord."
"So here's your challenge: two worlds. One is real, the other's... fake."
"Face—in both worlds—a deadly danger. But only one of the danger's is real."
"If you die in the dream, you wake up in reality. Ask me what happens if you die in reality."
"What happens?"
"You die, stupid."
"Time to sleep. {the birds start} Oh. Or are you waking up?"
"I'm kind of between ambitions at the moment."
"I've seen your dreams. Blimey. I'd blush if I had a blood supply. Or a real face."
"This is gonna be a tricky one."
"He's dieing and there's nothing I can do."
"Who are you?"
"Pick a world and this nightmare will all be over."
"It's a link between me and the Doctor! Bad Wolf here. Bad Wolf there. It's telling me I can get back! The least I can do is help him escape."
"If you go back your gonna die."
"That's a risk I've gotta take."
"If I could save the Doctor's life, try anything."
"Someone, something, is overriding my controls!"
"I want you safe. My Doctor."
