>>105834588Bill seems like a fairly emotional being, so I could see something like that being the case. He's a psychopath, but his craziness does seem to be centered around feelings of loss and lack of control.
Something that always kind of struck me as weird about the series was that Bill never once tried to make a deal with Stan despite their goals regarding the portal lining up fairly well. He would have been a prime target, even potentially better than Gideon. The best guess I've got as to why he sort of turned a blind eye to him was either because he knew that Stan was good at reading others and would have seen him for the con he was, or maybe because Stan was so like what he used to be, so like what he used to have, that he didn't want to acknowledge the man at all. It's certainly one way to look at all the strange similarities between the two, and their stranger avoidance of each other throughout the series.
