IMO implying
she "got what she deserved" is a very big slip, and has tones of **** mentality all over it. Like when a drug dealer takes out a snitch, it's simply what they believe should be done, i.e. "Snitches get stitches". I'm not saying that is for sure what happened, but to me that reads as she did something and got what she deserved. I think him selling drugs and her finding out and telling JH could definitely have happened. I think it's one thing to think you are dating a reformed bad boy, but finding out he is still up to those activities could be the proverbial straw on the camels back!
And no snark at all over here
I enjoy having theories picked apart bc it narrows the scope, but why do you believe it is a stretch?
