Random Tuesday morning theory (after seeing yesterday's video, combined with the Waterfall video and BH/KR texts.
We can all see what happened at Waterfall. KR had ghosted BH and he was mad at her and wanted answers. BA was drinking with him all day and appeared to goad him into confronting KR or at least telling his buddy, JOK, what was going on with her. He was so mad she ignored him and was all lovey dovey with JOK. CA tried to calm him down "not here, not now, and I've got enough going on that I don't want to get involved in this, so he walks home.
They get JOK to come to the house. He goes in through the side door, or garage, or around back or right into the basement, ikd. Either in the basement or backyard, BH approaches JOK with the texts/proof of KRs behavior and it doesn't go quite as planned. JOK is angry at BH for going after his girlfriend and perhaps gets in his face, maybe some pushing and shoving, BA jumps in and a scuffle ensues, leading Chloe to "protect" her master, BA. JOK falls and is mortally wounded and they know it and freak out.
BH tells BA, "hey...this is on me...this is all my fault and I'll make it right." Goes to CPD and goes into cleanup mode. BA insures no one in the house knows what's up and everyone eventually leaves. (I've never bought the hos long to die at 2:37 or whatever.) No one knows except for BA & BH (and Chloe) at this point. Perhaps BA tells his wife, and maybe she tells JM, but no one besides BA and BH need to be involved at this point.
Once BH realizes that KR said she may have hit him, he decides to go back to CPD, breaks the tail light, returns to 34F and quietly drops a few pieces in the snow. Everyone's else just jumps on board, trusting or fearing BA/BH and also hating KR. And even if she didn't do it, I am sure many of them justify that this is all her fault anyway, because she was "cheating" on JOK and started the entire thing.
