So Six is hostile? Damn never thought of escaping to test this out. I'm very curious to know if this change his reaction in DC as well.
You can turn him hostile with enouth Will + Though Control (psi powa), which break his "fear aura" and it makes him mad.
But of course, he has combat stats off the chart : over 50 initiative in average and 4 (or 5 ?) attacks a round with rather high damage . . . only a combinaison of morphine, 250+ metathermics-fueled cryoshield, luck, and save scumming allowed me to flee.
