Help? Brain is empty of the knowledge.

[kethni]

Okays, so my strange spiralling dark!fic (which I have no clever name for) is hammering on my brain again.
I need a character to be either an ex of Mohinder's or a very close friend of his. BUT I cannot work out in my head who is dead or alive :S  
I wanted to do Eden but I can't work out in my head if in the 5YG universe Sylar was captured by the OWI - thus resulting in Eden's death. 

Gah. Stoopid brain. 

Anyone got any suggestions for someone else? 

Muchly thanks.
