spoiler: wreav is irrelevant and wrex may turn out to be a bit parter after all (since we can kill him way back in ME classic and that the DLC would be fairly useless to that gamer population who killed him if wrex turned out to have a major part)

not to mention that in wreav-leader scenarios shep and wreav are buddy-buddies (or whatever that sort of relationship is, given krogan) by the time they meet at the FOB.

go look at the recently-added achievements. if they're legit (highly likely), apparently we're gonna have a pinnacle station 3.0 and we'll be facing spectre-level opposition at some point. to that last part, we're going to have to assume that if the secret enemy has connections THIS high up, that certainly restricts our likely candidates if it is indeed true that we'll be facing a familiar face (or plural).
