Ever since the final moments of The Walking Dead's latest midseason finale aired, we've been wondering just who in the hell has the guts (too soon?) to follow Rick & Co. around on their own turf. We always love a good mystery, but it's generally more fun when the cards are stacked so that we might be able to figure it out with the information given. (Potential spoilers start here.) It turns out The Walking Dead's boots-wearing stalker might be someone we haven't even met yet on any medium, and she might be from yet another new group.
