Ninja is now in the Sea Caves, still showing no ill-effects from his encounter with A-S. And I haven't been back to the Castle since teleporting out, so she is still alive and well.I did kill A-S before becoming a Templar, so I could kill her again after. But in an earlier game, I also killed her before becoming a Templar, and the sacrifice still became enthralled, so it's not that. And if I recall correctly, all my other sacrifices have become enthralled after about 5 minutes out of the Castle, even in the Savant Tower.
He's not wearing or carrying anything that would protect him.
