To get to this CG, in the beginning you should be passive. Don't provoke your uncle, then don't fight or talk back to Phestur. When you're trapped in his cabin, choose to wait and see what happens. Then when the BARAKAI crew boards the ship, don't escape through the airlock -- keep searching instead.
