I kinda feel like there are enough difference between the show and book, that, you COULD feasibly kill Maggie. She looked half dead anyways. So, in place of her running the show at Hilltop in a few seasons, have it be Carol or Sasha. I feel like Kirkman would do that because we all "know" that Glenn dies.
Also, was anyone else underwhelmed by the Hilltop? In the books it's bigger and spread out, whereas the show it looked like a single building and some trailers. Where was everyone also? Don't they have more people than Alexandria? Maybe I read it wrong.
