The Walking Dead gives Negan (Jeffrey Dean Morgan) his last name in "Here's Negan" — and it's a surname that creator Robert Kirkman jokingly revealed years earlier. Spoilers for Here's Negan follow. WhenNegan is exiled to an outpost away from Alexandria, where Maggie Rhee (Lauren Cohan) now lives with her son Hershel (Kien Michael Spiller), Negan remembers his late wife Lucille (Hilarie Burton Morgan) as he reflects on the events that led him to this point. When he flashes back to 12 years earlier, he recalls his pre-apocalypse life as a foul-mouthed school gym teacher: coach Negan Smith.
