The difference for me is more about Lester. Most guys just sit there and say, "isn't my dick bigger than your husband's? That means I deserve to fuck you more, just with you still married because it makes me feel more masculine and in control of others."
TA has Lester, who is taking the wife fully from the husband and leaving him, dumped in the gutter, with the wife's ful participation. Yes, he definitely like for her to say things about Dan, but action is more about him. He is insidious in how he worms his way into his life and takes over Sarah. Lester demands no less than Dan's destitution, unemployment, and broken marriage; while he takes Sarah from Dan, because he feels that he should be able to. Its part of what gave spawn to my idea that Dan was like a high school football player/bully, while Sarah is the Captain of the Cheer-leading team. Lester faced several of his most formative years as a victim of those type of people, even if his victim-hood is just in his own mind as he say what he lusted after and craved scooped up like some prize catch by people like Dan, while he was left with nothing. This is Lester's opportunity for payback and he will take it, come hell of high-water. That makes this more psychological to me and therefore different for me.
I agree that last chapter or so were meh, at best (as I also stated) but have hopes that the over-all arch of the story will lead me to, I hope what I want to see, or at least to a logical conclusion. Most of this is from conversations I have had with Don and his writing and I may be naive, but I keep hope until I can't. This does not poo on your opinion, just adds mine to the mix. However, I do totally agree that this Patreon system has led to people, including Don, to ignore the people who are not paying him, completely (where he used to listen and talk to everyone) and be surrounded by the LCD (lowest common denominator) in many cases and of course sycophants. Not everyone there is that, but a number of them are and any who do not pay are treated like shit by everyone on discord who does and Don is consenting through silence. If someone buys a Stephen King novel and sends him a fan letter, including his opinion and another checks his book out of the Library and writes the same type of letter, I doubt King says, "fuck you, Library asshole, you got no right to an opinion unless you pay me, beyaaaatch." (I was trying to picture how to write bitch with a Maine accent).
