Yeah, I'm not a fan of incest myself. This is just one of those rare cases that I really wish they weren't related. Yeah, there are other guys in the Order, but most of them are otherwise concerned with more important things then relationships. Of the three that I almost could pair her with, two are married to their jobs and the other has a duty that requires not getting close to anyone regardless of his own feelings. Plus as much as Lenalee loves her friends, her main reason for living is her brother. Yeah... really, really wish they weren't related ;_;
