I've started making a list in my head of pointless characters that nobody cares about or serve no further purpose that they can kill next week so they can keep the "shocking" deaths going. I'm thinking Podrick the squire's in trouble. Probably that Greyworm unsullied dude too.
Jamie, Tyrion, Brienne, Jon, Danaerys, Arya, Sansa, Sam, etc are all, of course, perfectly safe at all times.
