After X-Men: DOFP, Erik writes a letter to Charles.

Dear Charles,

I don't know if you will receive this letter. Probably no. Even if it would arrive at the Mansion, you wouldn't read it or Hank would destroy it. He would think it's the best

thing for you.

And maybe it is.

I did what I thought was the right thing to do. Shooting Mystique was one of the most difficult decisions of my life. Not only because it was her, my friend… But because it

would have been over for us. Forever.

On the airplane, I had already decided to kill her. I was trying to do the best for our race, Charles, I always will. Remove her, remove the problem. It would have been quick.

But when Logan told me that in the future we would have been together, no longer enemies, no longer on war, but us… I hesitated, in Paris. You were talking with her, and

she was wounded and trembling, and it was so like the old days that I hesitated. I hesitated because of you. You think I'm a monster since Cuba, but I think that trying to

kill the sister of the man I love and a former lover of mine it's the choice that made me a real monster.

That moment cancelled us and what we could have been.

The old days. Recruiting the kids, training them… I thought about it every day, while I was in prison. I thought about you, about all we had. You did well not following me,

after all. They would have kill you too, like Emma, Azazel, Angel. Angel… Did you remember? Our first kiss, in the strip club. She went to collect her things, and we were

hidden by a red curtain. You told me that you found incredible that I had such a sweet kiss. And the following weeks, at the Mansion… Training during the day, loving you the

night. It was the happiest period of my life, Charles. You were the best and first friend I've ever had.

But it's impossible, now and forever. It took a horrible war to bring us back together in an alternate future, and now that chance is gone.

I love you, Charles. I've spent eleven years missing you. I told you on the plane, while we were making love, while Hank and Logan pretended not hear. We are more

than friends, more than lovers. I love you, but I would harm you if it was necessary to protect the mutants. Maybe, I could even kill you.

We will meet again.

Erik
