What about K? He looked like he knew something(╯°Д °)╯╧╧

Based off of how it went down after K gave him the cigarette he passed out and then he woke up with everyone dead so K is most likely the one that killed everyone and set him up. Which is why he can’t remember anything and he just woke up to being covered in blood...

I think so too but for a moment I even thought that K liked him? I might be wrong tho
