Y'all it's not that confusing. He can't remember sh** and he's trying to figure out what's going on. The reason he can't remember anything is because he's apart of project called moritat. Moritat removes your memory or parts of it. He has trauma so he volunteered but because he did the thing twice or more some memorys keep popping up and traumatizing him. Those two are the only one left in that household who actually have brain cells so they rely on each other
