Off the plane in New Elmendorf, Annabelle would find herself in a world as close to the old one as could be found. Her and Morton survived the Knox Event, together, and here they would make their life together.
It took some adjusting but... in time... Anna took to hunting and working in the outdoors of this new Alaskan wilderness. Well, new to her at least. Life moved on from the days of struggling to survive, moving house to house and hoping the dead didn't find her.
Annabelle and Morton marry sometime in the following years. She gets that ring Morton had mentioned to her, and they settle somewhere close to Vic Thompson and Beth Pope. The ones who'd helped Annabelle and Morton find a place safe in the post Knox county.
As the years went by, Anna and Mort would babysit Beth and Vic's kids. And have kids of their own. Morton setting up a repair shop to work on cars, much like he had in Kentucky before the event. And Anna would hunt, happy to be away from it all. And to just... Live.
