The tears flowed down his cheeks as he leaned over the pool of blood where she lay. Her black hair drenched with blood her emerald eyes were now dull the only place on her face that showed no pain or sorrow was in the small smile which lay on her lips.
Without speaking a word she took his hands and placed them on her heart using the little energy that she had left. There was a glow and her blood formed a trance mutation circle around them, Ed hadn't noticed till the next thing he knew was that they were both standing in front of the gate.
He also hadn't noticed that she had been holding his hand till she had let go. Taking a few steps forward she turned to look at him, he saw that her emerald eyes had their glow back and her black hair clean of the blood. It hit him that she was wearing the same school girl uniform when they had first met.
Now what Ed thought. As though to answer the silent question the gates opened. Normally when one looked into the gates they would see the darkness filled with those damn little creatures, but this time there was a golden path way leading to a door at the end that Ed knew opened to the other world.
"Ed, I'm not dead yet, but if I stay here I'm as good as. I will have to go home to the other world, don't worry about me," she said.
Taking steps backward into the gate she turned and began down the shining path way. You will not have any memory of ever meeting me she thought as she heard the gates close behind her.
Alphonse later found Ed unconscious far from the pool of her blood, Al found a letter also that laid next to Ed.
Dear Alphonse
By the time you read this I have gone back
home and in trade to get here I have already
Decided that I would use all Ed painful memories
Of ever meeting me as trade, please Al let my name
be forgotten even in your mind, hide well or destroy
This letter for I fear he remember and live with the
extra pain of ever knowing me.
Yours Truly
