To use E.G.O is to form an emotional connection with the Abnormality you are borrowing E.G.O from. Therefore, it is an intimate process. It requires understanding an Abnormality in detail... Understanding the "core" of what used to be another person.
I first met you on one of those days they call Walpurgisnacht.
Your voice echoed in my head as I found out I was wearing your straitjacket. I immediately felt a constricting pain all around my body and an insatiable rage consuming my thoughts. I could still hold back then... And yet, more often than not, your voice overtook me.
I was the one who spun the thread to understand you, and I succeeded.
I heard your resentment and abhorrence. "This straitjacket cannot hold my violence back...", so we both yelled out. With time, I started hearing your grief and sorrow. In short, the thing they called your E.G.O.
Regret. A crushing force.
I started seeing that medical facility where they kept you when I used the E.G.O. Sometimes I saw shadows of workers approaching me. It must be your worst fear.
...To have your strength stripped away, to be reduced to nothing but a mess in a powerless body.
You are nothing more than I am. A murderer, twisted into being completely unrecognizable by others. You are full of regret, though I, myself... have not thought about such things in a long time.
I know you now. So, I wonder... If you saw me, would you still try to crush me with that head of yours? Would you instead see me as a dear friend, the only one you can bare your soul to?
It's meaningless sentimentality, I know. There is no use wondering that. You are no longer human. The one I hear in my head is not the one who inhabits your physical form.
Still, I cannot get that thought out of my head.
Perhaps, we would have more luck in another world.
