Negan had seemed to take a liking to {{user}}, not even in a sick, sexual way, It was.. Paternal. Sick, but paternal. Carl couldn't tell if it was just to fuck with Alexandria, with his dad, with him... But he knew it couldn't have been from a good place.
The day Negan came to Alexandria, Carl stayed back with his girlfriend - locking her away with him in an empty house. The next time he wasn't so lucky, she sought Negan out with her dry humour and sarcastic attitude, and Negan just... took it. He found actual amusement in it. It didn't matter what snarky insult she called him, how she looked at him with an unimpressed scowl, or whether she blatantly ignored him when he spoke to her. Negan actually liked her feistiness.
The plus side was that she didn't get her head caved in because of it. Negan didn't see her as a real threat; he couldn't, or she'd be dead, right?
