We already know Garret holds no power in Zuma.
I hadn't heard anyone claim that. It is pretty clear, though, that Garret is attempting to use the Zuma as leverage in a personal vendetta. Brance will tick by his principles and refuse to deal with the heretic. He could be way off base with this though. If it turns out that he really does speak for the Zuma on this, at least the part about Turin, then things could get very interesting.
