Billie Eilish was talking earlier in the week (to Howard Stern) about how Lorne had been coughing and wheezing while she was there. One of the new cast members (James Austin Johnson) said at the start of the week he was sick, and his wife is about to give birth, so they may have been better off just doing two at home shows in December. Various people at the show (and Lorne himself, probably) did not like doing those, so here we are...
I think things must have seemed under control until today, and that's why Lorne is pushing through, but it shows how he has had too much power for too long and the consequences. I hope NBC will step in and mandate at home episodes if need be, unless Lorne wants to stay off the air for months (the Olympics will be shutting everything out in February).
