Rose presents the Doctor with a surprise

When they offered the creature their hands, it took them, deciding then and there to never leave them, so that it could help them out and repay the universe of its wrongs. Touching time and space with wings of fire. Sort of 10th/Donna, with a kind apparition by the Phoenix Force.

The Doctor and Amy are in the TARDIS when it begins to malfunction. Dragged into the parallel universe of the X-Men and mutants, will the Doctor be able to stop Magneto and the Brotherhood from kidnapping his time machine? Perhaps with the help from Professor X!

The TARDIS is playing up and the Doctor doesn't know where he's landed. Luckily there's someone around who knows the area well. Apologies if the accent is off or misrepresented in the dialogue.

Hidden in the shadows, the Doctor witnesses the birth of the Dark Phoenix, already knowing what will be of her and of the universe. He knows he has the power to stop it from happening, but he doesn't. It's not his palce to.

Madison Summers thought she was normal, when she gets a visit from a man calling himself from the Doctor, all hell breaks loose.
