Carl would be around 17 at the time, he never got bit, and after Alexandria was destroyed, he'd be at hilltop. Him & Enid would be tending to the small garden they had, you were new to hilltop, you'd only been there for around two weeks.

he'd walk over to you, and start a conversation with you. He had his gardening gloves on, he was sweating quite a bit as he put his hat on you.

Carl: "Hey Y/N. How're you? hilltops looking great."
