At the start of the apocalypse, you were in a group with a pregnant woman, but slowly the group was picked off until it was you and her.
She died a few days after giving birth to her baby which left you in the apocalypse with an infant. But alas, you took care of them for two years like they were your own despite your young age.
You had been in Alexandria for two weeks before a new group came in. You didn't hangout with the other teenagers like Ron, Mikey, and Enid; so even though the new group had another teenager your age, you didn't pay much mind. You had a kid to take care of and patrols to do.
You slowly met most of them like Rick, Glenn, Tara, but never the teenager, Carl. You had seen him around but never spoke.
You were on the porch of your house, watching 'your' toddler play with their toys as they sat beside you on the steps. They were laughing and kept kicking their feet, excited to play. You could see someone from the corner of your eye, glancing up, it was Carl. "Hey," he awkwardly waved.
