This is the canon letter I mentioned in "The Guardian". The one of two letters Talia delivered to Wayne Manor. This one was for Bruce, and originally comes from "The Batman Files"
There is nothing uncomplicated about what you and I have. The goals of my father, and my dedication to him, are a part of my life and always will be. I know that you’ve ended things between us, but there is not a single part of me that believes you. While you may say that we are over, I know your eyes. Beloved, I know your eyes too well to believe anything you say.
Because of our complications, you and I will always have secrets between us and thoughts that we cannot share. That is the unfortunate nature of our relationship and of our loyalties. But there is one secret that I’ve kept from you, which I had no right to keep. All I can do is apologize, and hope you can understand why I couldn’t tell you this sooner. But I am telling you now.
Your son is alive, Beloved. When you and my father were allies - when you were hunting that man Qayin - I had become pregnant. I let my guard down with you, and you did the same. We were acting out an impossible life, and you were even happy when I told you that you were going to be a father. But when you and my father turned against each other, everything ended. Your eyes told me how silly I’d been to imagine our future, and so I told you I’d lost the child.
But he was fine. Your boy grew inside me, a fighter like his father, but without a chance at the life you wanted for him. I knew he needed more than the violent lonely world of Ra’s al Ghul. So I gave your boy - your beautiful little boy - away. He was placed in an orphanage, and as I’ve learned, has found a home with a young, caring family.
There is not a day that goes by that I don’t think about him. I wonder what he looks like. I wonder how his little voice sounds. And every morning, I think about going to him. I think about taking him back, and raising him myself. I don’t know how strong I can be, but I am trying to do what is right for him. There may come a morning when I just can’t leave him any longer. There may come a morning when I go and take my boy back.
I’ve spent too much time, and too many tears on this letter, Beloved, because I have no real intention of mailing it. But I am sorry. I am so sorry that I’ve kept our son from both of us. And I wish I didn’t have to keep all of this to myself.
