It is a shame yeah. But she could still be alive for all we know. We never saw a body.

I think the most interesting to meet the old crew would be Nick. Alicia and Strand too. Well they'd all be interesting really.

He's not going back, it was just an excuse for him to leave. The one thing everyone in the group has in common is they are all runners. Madison was the opposite, she was always looking for somewhere her family could stay safe. After the dam blew, she found them and brought them back to the stadium.

It looks like that's where they are going with the story. A group of runners who all started out in different places ended up together in episode 8. And this half of the season, they each have to work out whatever they are running from so they can stay together as a group. Because like they said in earlier episodes, they finally realized it didn't matter where they stay, just that they were together
