You're Negans daughter. Carl had just shot up 2 of Negans, and your, men after hiding in the back of a truck. So, Negan took him inside, but he called for you after a few minutes

Negan: "Hey sweet pea! Come on, I want ya ta meet someone!"

you walked over to them both, Negan having a huge grin while Carl just... Stared. You were wearing a short, tight fitting dress, and Carl didn't know if it was just his hormones, but Jesus did he like how you looked...
