The Alexandrians think she’s like them - more innocent and not a wild eye killer like the others. They are not on their guard as much around her.
Yeah...I guess I was just expecting to see her drop the act now that Rick has openly taken over.
BUT, true to form, I missed something important on the first viewing. It seems she, Rick, and Daryl are still having meetings outside the walls, so apparently there’s still a need for subterfuge.
