Now that I'm replaying ME2, I do wonder what the impact will be of Aria if you've aided her with her Patriarch and the conspiracy of the mercenary gangs. Does anybody have an idea how that could impact the fight against the Reapers?
It certainly could have an impact on the broader conflict with the reapers.
Shepard will have to unite the Council races (as well as the Terminus systems maybe?) against the Reaper invasion forces, so the power struggles on Omega might play a role in that.
