Ukraine was a choice in my mind and Charles Fei-Ong comes in second. He's been active in the proceedings, but still keeping very distant in a manner of speaking. He also seems to have a connection to you, coming from this place called "Mayfield". But I agree, Ukraine is certainly the more likely of the two.

Eliminating a Country at this point may be the best way to go. It would take suspicion off of Prussia for certain. Aside from Holden and Ada, the Hunters left haven't been seen as suspicious at all really.
