There would be riots in the streets if they killed Daryl. It would end worse than open carry at the RNC this year.
Also I would riot in the streets if they killed Daryl.
But really, I wouldn't even call this a fake out. Dwight blatantly said "you'll live" after that shot. I'm like 90% sure that wasn't how they filmed it and they actually added that line sometime recently so people wouldn't get super pissed like they did about the Glenn fake out. That, and, well, this is only going to last a week. Whereas the Glenn thing went on for what, a month and a half?
Also, calling it now, Morgan is gonna find Carol, teach her his ways, then die like that guy that saved him, probably to the Savior stalking them. Carol will then return to Alexandria as the new Morgan/Herschel/Voice of Reason.
Also, reasonable chance Michonne or Rosita actually die, come to think of it. Michonne could die because Rick is overconfident or Rosita because Abraham will realize he was an idiot and actually did love her.
Glenn won't die here because all signs point to Maggie dying (fucking baby armor) and there's no point in killing them both at once. Glenn will get back and find out, Enid will have some important message for Glenn entrusted to her, Glenn will try to run off like Enid did before, but this time Enid will talk him out of it the same way Glenn got her to come back before.
And as for how Glenn, Rosita, Michonne, and Daryl get rescued (minus whoever might die), I've got 10 bucks on Carol stumbling upon them and non-lethally saving them.
Alternatively, Maggie doesn't die and Glenn actually dies, since in the comics he's about to die from the arrival of actual Negan, who has been cast and is supposed to appear this season. There being only one episode left, he will appear next episode.
