The day I had almost lost you, do you still remember that? Of course, it was the day we had tried to bring back mother, the day we had crossed the lines of the laws of alchemy. We had everything planned out, but little did either of us know that it wouldn't turn out the way we had expected. We had only created a body without a soul; a homunculus.
I'd forced you into listening to me, I remember. You kept on telling me that you thought what we were doing was wrong; that it didn't seem safe. I now realize that you were right; that I should have listened. If I had, none of this would be happening. This pain is worse than the pain we suffered from just losing our mother. And you, you're not the same. A soul trapped in a suit of armor is all of you that remains.
Even worse, what if I hadn't been able to save your soul just in time? I would have lost you forever, right? I couldn't imagine life without you; the only one I had left whom I could completely trust. This whole time, you've been there for me, so it's my duty to be there for you as well. You've protected me, cheered me up, and I guess even loved me. I guess mom was right when she said I'd love my new little brother. Besides, you're one of the only people who could bring a smile to my lips after mother had left us. I would have been alone. I wouldn't have made it this far without you. It still hurts; knowing the pain you must go through. It hurts me too.
If all were lost; if you were lost; there would be nothing left in my life to look forward too. There would be no one to bring a smile to my lips, no one to cheer me up, no one to protect me, or even to be loved by. I remember telling you all this, and I remember you telling me, that's what brothers are for.
