I think they will just brazen it out. I think they will always have people they have “discarded” who have been used, abused, like your Bill Cole or Martin Hemmings. The will have some less-close acquaintances like school friend, maybe some locals, who aren’t so deep in it to as feel they’ve been lied to.
Habitual liars really depend on people not speaking with each other and joining the dots. They would much prefer to spout their lies one-on-one, it’s more effective that way, when you can look a person in the eye and know you’ve ground them down into believing you. I wouldn’t expect a mea culpa.
I have basic compassion that they're not in a nice position. I don’t believe they are shunned by everyone. Most people find it easier to be pleasant in the shop (although SalRay could take offence at Jesus himself smiling and wishing her a good morning as she entered the post office, I’m sure!) and they aren’t ogres, I’m sure they’re pleasant enough if you don’t get tangled up in their “woes”.
I think Tim might have some ill health, which is unfortunate but Idont think he was ever previously terminally ill, not in France, not on the Salt Path, not at the Cider Farm.
