A/N: When I saw Trust No 1, I thought of all of the other things Mulder might have wanted to say in that email, and I decided to write this. The letters are in no particular order, except the first and last. And I wrote them before I saw The Truth, so there's no mention of anything that happens in the finale.

Lonely

Dearest Dana,

I know that I cannot be allowed to send this. You would be the first to tell me that it is too great a risk — to all of us — for me to contact you. Nonetheless, I feel compelled to write to you as if I could send it, longing, as I do, to see you again.

It has been only a few days since we said goodbye, yet your absence is like a knife in my heart. I thought I knew what loneliness was, after losing my sister, my father, my mother. I was wrong. You've been by my side for so long now that being without you is like missing a limb. Try as I might to bury myself in what few avenues remain to me to solve this, to find the truth, so that I might return to you, I am all too aware of your absence. Being unable to even speak to you, to hear your voice on the other end of the phone, is the worst kind of torture.

I miss you.
