Right, I think I see the issue. I originally meant for the drives to be stored with the weapons in the main armoury upstairs, where Duncan and co are heading, but went with the flow when it was implied they were elsewhere. Word of God now states that the drives are being kept in a secondary location known to the soldiers, probably a lab or storage room of some kind on the lower levels. Right at the bottom of the shaft is the generator. Since Jericho is leading the main group off to sabotage the power, Xerox can lead whoever wants to go to get their drives.
As to whether shit kicks off due to the actions of either group... Well, I like to think I'm a sadistic GM.
