Wow, this is so close to what I believe it's almost as if I'm reading my own words, lol. I absolutely agree that it pissed the He!l out of Lori that she did not receive a dime from Charles Death, and certainly she could have taken that rage out on JJ, whom she had started to resent.
My feelings around all of the non violent deaths were that they came from Lori, that medicine/poison is her MO. JR, Tammy, and Alex all feel like her. And, I believe she may well have given both JJ and Tylee a "dose" of something before cutting off their airway (or letting someone else finish the job, so to speak).
Alex and his strange sisterly obsession made for an excellent gofer, she well knew how to manipulate him to do her bidding. CV, was prob. supposed to die while LV and Tylee were gone (scary when you think that JJ was staying with him at that time also...) but Alex intentionally or unintentionally blew it... the same way he 'missed' shooting Tammy and BB. I do wonder what the final straw was with Alex though... was it just that he knew to much? Notice it was timed so that Lori was yet again away in Hawaii...JMO.
But really, the only true mystery in this whole sorted story is where did they put the kids (remains)?!
What I cannot fathom is that however it actually went down with her kids, Lori def. played a role, and that's some serious mental illness. Narcissist believe they are smarter then everyone else, even when they are so obviously not and Sociopaths have zero empathy/ sympathy therefore once a person stops being useful to them, they drop them like yesterdays news and take off. Crazy and very Dangerous!!! MOO!
