Trying to Find my Friend

Zelretch, I'm looking for one of the homonculi as well, though not Brutus, I'm looking for the one who fought somewhat similarly to myself, and required quite a bit of work to break out of the control.

Also, I'm curious about the perfect homonculus we encountered in what I assume was the past, in that alchemy lab we visited when we were going through various times. If you could contact me with information on either of those, I'd be most grateful.
