Some theories that I've read conclude that Mikasa and Levi, both being Ackermans, were told about the building of the walls. Or at least most of their family members know or remember. Other theories say that Levi knows considering that he had a more likely chance of being told, looking back on his history. While Mikasa probably didn't know since her parents were killed when she was young and they didn't have the chance to tell her since she wouldn't've understood at that age. I'm a little confused here, but it makes sense. I would just like to know if this is a useless theory that doesn't fit into the story or if it could actually be possible. Does anyone know?
