Aerith Prays ↔ FF VII: Crisis Core
I think [Spoiler (click to open)]Sean is Amanda's mole, maybe as a last-ditch effort to get Alex and himself out of Division permanently, albeit it's a deluded notion on his part. I thought it was Sonya at first, but she sent off so many red flags with her switch in attitude towards Birkoff and wanting to suddenly work with him that she would be WAY too obvious a pick.

Hopefully the writer's stay away from the predictable choice.
