Well the part I'm at in the show, that stupid Governor attacked the people at the prison and sent the van through the gates and released all the zombies, that was the very last episode.. man it was intense.. baby Judith is all I care about at this point. D: And of course Daryl, but not his stupid brother. God, I hate Merle. >.<

Anyways, so since my guess is they leave the prison since that happened, we can do right when they leave the prison. Maybe our two character's can be sisters? And they are boarded up in a warehouse or a small home or something?

And since you are better at the badasses, you can be the badass sister! :D
