Lauren Cohan, who stars as Maggie Rhee (née Greene) on “The Walking Dead,” has paid tribute to late former co-star Scott Wilson. Cohan shared a photo taken with Wilson to her Instagram Monday, showing the pair hugging and smiling. The 76-year-old Wilson died Saturday following a battle with leukemia. On “The Walking Dead” he played stubborn but wise farmer Hershel Greene, whose legacy lives on in Season Nine as the child of Maggie and Glenn (Steven Yeun) is named in his late grandfather’s honor.
