the fact that the righteous gemstones teases us with the idea that lori might, malevolently, want to take aimee leigh's life and then turns it around on the audience by saying that yes, maybe lori does want aimee leigh's life but not out of spite, but because her own life had been so inadequate.
aimee leigh had a loving husband who gave her whatever she wanted, kids who despite their shit attitudes love each other and their family, and a flourishing career. lori had an abusive alcoholic miser who treated her like shit and put their kid in between their marital conflict, and after her divorce is possibly actively harming or killing anyone she tries to get close to, and most certainly still has their kid wrapped up in whatever he's doing.
of course now that she's free of that, even if corey and cobb haven't let go, she wants to feel like aimee leigh.
