kind of off topic, but didn't anyone else find it kind of odd at the end of the game when Ragna tells Rachel that he beat Terumi while Rachel isn't really all that surprised? It bugged me because through out the entire game she kept telling him that he could not win, and when he does she doesn't even seem all that surprised. Keep in mind she didn't know that he had absorbed the idea engine.
Does that mean that she knew that he was going to beat him in advance?
