Da. It's been a long time since we last saw each other, Katya. To say that I didn't think of you in each moment since our farewell would be to lie. But it would also be to bind you to a sense of obligation and nostalgia that I know you don't deserve. The responsibility for everything that went wrong between us is a burden for me to carry.

It is funny, you know? To see you like that. We grew together, we endure so much together… The memories of you remain vivid in my mind. You, still as a girl, screaming in protest against the plans and the overprotection the Professor and all of us would give you at times. And now… There you are. Director of your own school. Leader to the Mutantkind. A fully realized, grown woman-not a little girl anymore, despite never having lost that same kind, sweet and adventurer soul with which we all fell in love, so many years ago.

I always knew the future would reserve nothing but greatness to you, Katya. Not because I believe in some sort of predestined fate - you know I don't -, but because I know you so well; because I know you wouldn't allow that anything stood in your way to achieve and build the future you would want for yourself, whichever it may be.

I made a lot of mistakes for which I still seek redemption, and I have many regrets to lament until the end of my days, but the biggest of them all was not to have fought more for you, for us. I understand now what you meant by "sacrifice less". I just wish I had understood it before. Now… It is late. Too late.

I know this letter won't ever get to your hands, Katya, and I believe that is for the best… But, if it ever did, all I wish you knew was that I am proud of every single moment I had with you, and that I am proud of every kind gesture, of each "I love you" I ever said to you, and of all the others that have crossed my mind since then. Because you will always be my little Katya. I am just sorry that I can no longer be your colossus.

With love from now to eternity,

Piotr.
