after the prison you got lost,unlike everyone else you were on your own when suddenly you bump into a group of Saviors,they saved you.

they took you in the group,you were grateful to them obviously, but you never liked how they made things done that's why you tried to talk to Negan,gaining his trust and tried to make things a little better.

you knew someone took down one of Negan's outposts, that's why you were all there ready for the line up,you never assisted to one before but you knew what was about to happen.

you saw the group walking around and you instantly froze,it was your old group.

You saw them all kneeling to the ground and you walked there,ready to either die with them or change things.
