The fandom will kill him, Leo and Reyna are probably the most popular characters of the fandom. If you look at PJO he only really killed minor characters and Luke but there was no way to save him and make him look good in the end except for killing him.

I think characters such as Dakota (noooo!!!), Lucy, maybe even Drew or Octavian and Hylla will die. They're not major characters yet at the same time they do have a bit of development so that's really what RR is looking for.

Of course it doesn't make any sense that all of the seven should be kept alive but they're special snowflakes so he's not gonna kill them.
