Look, I get that the show isn't exactly following what we know by now to be proper mask etiquette, how we're supposed to deal with Covid, social distancing, etc. But this is a medical tv show. One where, pre-Covid, we would see the surgeons scrubbing without wearing masks and then somehow having them when they were in the operating room. Yes, in a real ER, the dad of the leukemia girl would be wearing a mask, the hospital staff giving the little tribute on the roof would know they don't remove their masks to speak somebody's name, that a guy dying of Covid wouldn't be dying in the ER but would be up in the ICU and would have been given remdesivir and steroids, etc. It's a TV show! Would we be happy if all the characters were wearing masks at all times except to eat? No, that's silly. The show isn't paying these pretty people to be wearing a mask all the time.
I think one thing that might be helpful would be if before the show ran, they just ran some text like "We understand the importance of wearing a mask and socially distancing. The events depicted in this fictional drama are for entertainment purposes. Please follow proper Covid protocols and stay safe."
