-Synn, why did you put your new mirror by the bed?
-I wanted to watch us while we fucked.
-But you were looking at me the whole time, so there was no point in it. And it was laid against the bed and dresser so you couldn't see even if you looked.
-Ok I get it, I'll move it. Damn woman get off my ass >.<
- :P

Synn got a new mirror on one of his little hunts for pretty pretties and decided he wanted it in his room but never got to the point of where to put it so he just laid it against the bed. Yeah Ichi figured him out and bugged him about it but next time he won't leave things next to the bed.
And unfortunately what you see before you is not a trick mirror, you're seeing Ichi....and Ichi....When she was still young and the evil scientist Reznor was experimenting on everyone, Synn included, he only used alittle toxic formula on Ichi and had put her aside to continue later since all the other children kept dying after an experiment, but she was kind of forgotten for a bit. Synn had no idea when he rescued her that Rez had done anything to her, and never thought about it even when they found each other again 16 years later. But what is this mirror trying to tell us.....?

To be continued.
