Just finished my second watch, and noticed something at the very end I didn't notice before. They show Carol walking to the edge of the upper balcony on the brownstone overlooking the community. Its extremely brief, and I had to rewind and pause, but she appears to be holding a map in her left hand and a compass in her right hand. The night before she told Daryl "we should have gone to New Mexico". And is she planning on doing something crazy on her way out, like killing Alpha? If she is planning on just leaving without killing Alpha and Beta, then it wouldn't fit with her possibly being the one who helped get Negan out.
