Samantha, a 45-year-old woman in the Sanctuary is treated as an advisor, somewhat trusted but Negan still strives to exert his authority over her because she refused to become one of his wives because he killed her husband in front of her. She gives him the best advice she can to earn a position of trust in his crew.
This story takes place after Negan kills Abraham and Glenn and takes the injured Daryl back to the Sanctuary. Sam advises against this course of action and Negan punishes her for speaking against him in front of his men.
Non-canon twists: Dwight’s season 7 attempts to break Daryl never happen. After Daryl is patched up, he is courted by Negan who tries to recruit him to become a saviour. To reward his men, Negan awards them various women who opt for this “job” as a way of earning credit within Negan’s system. Whether for the night or for longer, the only agreement Negan insists on is that they are not taken against their will. To punish her for speaking out, Negan adds Sam to the rota of available women. When her spot in the rota comes up, she gets awarded to Daryl.
