What sin was that Ellie girl again? Was it mentioned? I didn't remember.

I think she has lust and envy is her weapon

Hmmm.... Thank you. ヾ(☆▽☆)

No, Envy was the weapon that Knight own, you know the one who asked Fate to join him.

Nope :), spoiler



The knight was merely envy's puppet and the real owner is ellis.
