Million dollar question, is Chris' wife cheating on him?
Just thunking aloud here, but that line about having 'no idea how she was exposed' is unlikely. Usually even if people wear a mask they can point to some event where they were in contact with other people, such as shopping or something inconspicuous. But they have 'no idea' whatsoever? Unless they're actually deluded enough to believe SCIENCE! and masks make them literally impervious, which, in fairness, I'm not ruling out.
So if Chris' has no idea, two options present themselves. Either he's intentionally misleading because the most likely place she would have got it was at a protest or or meeting that would make their side look bad, or Sarah is going places without Chris' knowledge. I doubt the first because Bob refused to go out to protest because of health conditions, and if they did go out, they'd be virtue signaling. So Sarah going places without Chris knowledge seems more likely.
Maybe she's just getting out of the house to get away from his increasing derangement. Wouldn't you? Put yourself in her shoes. She's already got a deranged, genocidal brother-in-law, and now her own husband seems like he's becoming one in the same. But catching the virus generally requires close quarters or direct contact, so unless she's out there shaking a lot of hands like she's running for president, I can only think of one thing that fits the bill. Notably if she got it and he's negative, it's telling that Chris and his wife haven't been close much either, so it looks like Chris' sex life is in the tank. I guess that's the trade off for chump change on patreon. Hope it was worth it.
Ladies and gentlemen, place your bets;
1) Are Bob and Chris dumb enough to think masks = 100% protection
2) Did Sarah catch it at a LGBTQ+ event/BLM protest/Biden 'rally'?
3) Is Chris becoming a literal cuck?
