Spoilers for "Here's Negan." When Negan flashes back to the earliest months of the zombie apocalypse, he remembers his cancer-stricken wife Lucille (Hilarie Burton Morgan) and how he left her on a six-week search to find chemotherapy drugs. Negan gets home to find his wife has died by suicide and reanimated as a walker, but he can't bring himself to put her down — so he sets their home ablaze to the tune of Negan and Lucille's love song. The scene is the first time viewers find out what really happened to Lucille: Negan previously confessed to Father Gabriel (Seth Gilliam) that he was too "weak" to put his wife down when she turned, later telling others about his wife's illness. But Negan never revealed that Lucille took her own life not long after he set off on his six-week quest to find medicine to treat her pancreatic cancer.
