Yes, that is L from Death Note, and I think this is one of the only cases where I'm not going to argue any more logic. Alexi doesn't know, period. He just doesn't. Even if it doesn't make sense, he doesn't know. His brother presented him with profiles, reports, outlines, redacting the names from each and every one because he knew his brother didn't want to know. He has no rich friends to discuss things with, he doesn't listen to rumors, he doesn't listen to radio, or watch TV, and he ignores most talk about the rebellion, to busy with his own plans for slavery. You can think about it what you will, but the fact will remain: Alexi doesn't know Erik's name. Mois does, because he was the one doing all the research, but Alexi, doesn't. I'm not upset, so please don't take it as such, I'm just not sure what else to say. It is what it is, and I can not change how it is.
