Yeah I've connected the dots... The Duke is the most likely killer, MC wasn't drunk he was prob given the pills that made him obey every single thing someone orders him and erases the memory the moment the drug wears off — that's why he didn't remember anything after he got banged and why he's preggo
The Duke was most likely pis*** or something so he went all psycho and killed those who resembled him and stuff
Lemme know if I missed some stuff and/or got some things wrong
