The inquisitor will be explaining where all the insurgency came from shortly...  if you survive.  He engineered the meeting precisely to bait a trap that the heretics couldn't possibly resist, putting a Rogue Trader, an Inquisitor, a Crusade Commander, and a famous hero of the Imperium all on the same ship, to provoke them into attacking.<br/><br/>You can be assured that the heretics have committed pretty much everything they have to this one, and that it'll likely be the final battle against your own heretics for a while.<br/><br/><br/>(I'm also curious whether the possibility of intercepting the torpedoes with shuttles has occurred to anyone.  You could probably disable at least one torpedo if you talked the dreadclaw into a suicide mission.)
