Replay is the story of how after Magneto of an X2-ish future succeeds in the unthinkable, Charles sends his consciousness back to 1962 to guide Erik away from the path that will lead to the genocide of the human race forty years hence. Charles knows Erik has always loved him, and intends to accomplish his goal through a totally bulletproof plan involving lots of sex. But there's something Charles doesn't know, and he's in over his head from the start....

Erik's side of the story is a little different.

Erik's spent fifty years being a figurehead and he's ready to leave that behind. Luckily, so is Charles.

(aka Old Retired Dudes in Love)

Four years after the events of X-Men: First Class, Charles Xavier finds his X-Men on the losing side of their continuing battle with Erik’s Brotherhood. Azazel and Mystique have a child in secret and, unwilling to raise Kurt in the midst of Erik's war, they give him up to Charles to raise at his school for the gifted. He agrees to do so, on the condition that they visit their son regularly. This leads to tenuous contact between the Brotherhood and the X-Men outside of the battlefield for the first time in years, and both Xavier and Magneto realize that the lines dividing them are not as clear-cut as they previously thought.

In which Santana Lopez learns the hard way that a life can never be ruined, only lived, and lived, and lived.

Erik accompanies Charles on a trip to Washington and tries to stay out of trouble this time.

Set one year post movie, Charles overloads himself in Cerebro, and his mind goes walkabout; wherever he is (and he’s around), it’s not in his body. Erik temporarily takes over the school in his absence, and finds that there’s little time for resentment or hatred when he’s busy organizing assigned reading for English lit, keeping the youngest children out of trouble, and trying to talk Raven into wearing clothing for the boys’ sake. Somewhere in between taking responsibility for the students and dreaming Charles’ dreams every night, he manages to remember that he’s something rather more than a weapon. In other words: A Love Story between two Gentlemen, told in Prose, Epistles, and Nonsense Rhymes.

Charles smiles at the pawn in his right hand. "That was when I understood how easy it was. If I operated without limits, I could remake the world. Isn't that the best argument for restraint?"

Looking back, that should have been his first clue.

The most powerful telepath on the planet could never be a pacifist.

He opens his eyes, and he is Erik Lehnsherr. He is hardly more than a boy. And he is walking through the mud on his way to the gates of Auschwitz.

And that’s how Logan joins Charles Xavier and Eric Lensherr in working with the CIA.

Hey, he never said he wasn’t an easy date.

After Magneto of an X2-ish future succeeds in the unthinkable, Charles sends his consciousness back to 1962 to guide Erik away from the path that will lead to the genocide of the human race forty years hence.

Charles knows that Erik has always loved him, and intends to use this knowledge + sex to seduce Erik away from his ideals in his youth.

There's no way this well-thought-out, sensible, debugged and 100% bulletproof plan can possibly go wrong.

After the eventful Christmas in Harry Potter's fifth year at Hogwarts, his godfather gave him a badly wrapped package. Inside was something Harry could use it to get in contact should the need arise, Sirius said. Harry resolved never to use whatever it was -- he would not put Sirius in danger. When later that year Harry was shown Sirius in terrible danger, he did not think of using Sirius's last-minute gift. Hermione, however, did. This is the story of what happened after that.

"Right here, right now? I want to stop you from cancelling Firefly."

Following a rather different ending to 2.10 ("Sweet Dreams"), Merlin and Arthur head to Olaf's kingdom of Valden to put things right. In the process, Merlin racks up an impressive series of treasonous crimes: insolence, incompetence, tripping while running for his life, and accusing the crown prince of snoring are only the beginning.

"I wasn’t hiding it from you. Honestly, I didn’t know for certain until yesterday, which I think we can agree was bad timing and not the sort of thing one springs before the heat of battle," Charles says earnestly.

In which you'll find chess dates which aren't dates (or maybe Charles is wrong about that). -- Based on First Class, this turns (slightly) AU during the beach scene.
