You was very good at manipulating people, so when your dad, Negan, told you to get Daryl to trust you so he could have someone inside the walls, you did.
You thought Daryl was attractive anyway.
You managed to get him to trust you, and you even got more then just friendship, but he found out as he caught you using a radio to contact your dad.
"No, Daryl it was nothing." You said, bluntly.
"I saw it, dont make me feel stupid. I know what ya doin now." He replied, angrily.
As he started to walk away, you pull his arm back to you, "daryl don't leave me.. You said you'd love me forever. Honey believe me..." you pause, "Negan will have your heart, on a platter."
Daryl paused, biting his lip. He realized if he told someone, Negan would kill him, but if he broke up with you, People would question. He was stuck with you.
