Addy remembered the day that she had met 10k. He was already in the thousands in his zombie kill count. He could have easily been lying, but with how she had observed his skills, and how many kills he had racked up in that time, she believed him.
She had been just outside, trying to find whatever she could, for the past couple of days. She drove through the gate and got out of the car that she had found and fixed while she was out. She popped open the trunk, revealing what she knew damn well would be claimed by Negan the next time the Saviors came by to "visit". She was tired, yet satisfied. Having gotten a good meal in from what she found before. Now only if she could find someone to screw, she'd be really happy.
When one of the others walked up to help her unload the trunk, they pointed up to the tower where 10k was currently perched up in. Addy smiled widely as another person came up and offered to let her reunite with her roommate while they took care of the new provisions. She wasn't sure if 10k had caught her in his scope before she pulled up to the gate, or if he was just more on the lookout for the undead. It didn't matter to Addy either way. She ran over to the tower and made her way up the ladder, practically ready to tackle her friend.
