over 11 seasons, an indomitable walker-killing mom and onetime leader of the Hilltop Colony, is venturing into NYC with Negan (former Alexa cover star Jeffrey Dean Morgan), the reformed baseball bat-wielding maniac and killer of Maggie’s husband, Glenn (Steven Yeun). It’s an inspired pairing, and things are gonna be awkward: In the “Walking Dead” finale, Maggie tells an apologetic Negan she can never forgive him.For a performer who’s spent more than a decade steeped in fictional death and destruction — yes, the walking dead on the show can be metaphorical, but also, there’s a lot of killing — Cohan really comes alive talking about the experience.
