Elias's Photographic Memory

A scene of Elias' daring rescue of Shizuko, he encounters Ai, the last remaining remnants of Roc, saying that the time has come for our father will soon consumes the world. Elias tells her why they want Shizuko, she simply tells "it was our fate to rejoined him and soon, Sissy will become a demon to destroy the world". Elias, disgust of this, tells her that she doesn't understand for a remnants like her. Ai, realises that Elias was in love with Shizuko, mocks him for his failure for saving a woman (Lucretia) from Tarquinius, but Elias answers that it was her fate to stop him from being overwhelmed by Janus even if it cost to her life. When Ai says that he made a mistake for in love with a monster, Elias retorts this by saying "She's not a monster..YOU AND YOUR SISTERS ARE!!". This snaps Ai, fearing that he will take Shizuko away, attacks Elias, who has a flashback he has with Lucretia who jokingly at the end by saying "if you want to be smarter, you have to be a predator". This makes Elias remembers his conversation with Lucretia and engaged battle with Ai with his photographic memory.
