Overseeing the operation is Mother Curie, who believes firmly that she is doing Atom's will and helping the world grow, and they find that consecrated Aqua Pura is actually much more potent than any other "dirty water." She has prepared a rich and varied history to read to her "flock." Should you find her in her second state; she has received her greatest wish, as she bathed in the light of infinite candles, and reached a higher realm of consciousness. In fact, this worked so well, her mortal corpse has become a frothing, savage ghoul with no knowledge of your previous interactions.
Mother Curie III appears as a hostile feral ghoul reaver if Megaton is blown up after Broken Steel.
Although holding a .32 pistol, Mother Curie III is an extremely peaceful character, and does not become hostile if you killed Brother Gerard in order to enter the Monastery, or even if you flat out tell her that you're going to wipe out her cult. If threatened, she simply states that she expected some form of religious persecution and that she refuses to respond to violence with violence. If you initiate combat against the Holy Light cult, Curie will simply cower and flee. Her feral ghoul reaver and glowing one followers, however, are not so forgiving and will attack.
