Kuanjita, mysterious woman. Like Dreamless said. Very suspicious. ^^
Lucille theory that Eric's memory is blocked and it required a similiar horrible experience to remove the block.
This scene comfirmed my tought that Eric has been in that cave before and he was present when the expedition members got killed.
Being there again is the right condition to remove his memory block.
Eric sucha tragic character, only known him for 2 episodes but he has quite some depth in his character.
He also seems to know more about Madlax and probably about Margaret too.
She materialized when Eric chants the Elies writings.
I forgot his name, but he seems to be deceiving the masked man with misleading information. He might have different agenda from Enfan.
The farewell letter from Eric to Margaret.
Theories. I believe the Elies writing bring out the dark desire inside the person, and the result was the world where Reticia stands, which is in ruins. That's why when Reticia showed up in front of Eric, she called this world is too normal and it's not a place for a person like Eric who has a monster inside him.
I think Reticia is the Deity of that dark desire.
I still have a big question. What's Eric connection with Margaret and Madlax in the past? Did he have anything to do with Margaret disapearance?
