I've been mulling over the rescue attempt at the Arena by the survivors from the Other Tower. Here are some questions that have occured to me:

1. We know that the survivors of the Other Tower had to run for their lives, unarmed and without supplies. Granted that they had pre-designated rally points with caches of arms and supplies. But how did a group of disorganized survivors get organized to launch the rescue attempt? Who organized the rescue attempt?

2. Who were they trying to rescue? We know from Kalani's account that he was being held with someone named Martin, whose origins we never discover, but who had apparently been at the Arena for some time. The next prisoner to show up was Samantha, who was grabbed from the rescue party. Did the group from the Other Tower attack the Arena to rescue Kalani, or were they hoping to find other survivors there? For instance CJ, or Shaun, or Hope?

3. Did a group from the Other Tower actually go to the Water Works, and if so were they part of the rescue attempt? If they were part of the rescue attempt did they go back to the Water Works again afterwards?

4. What happened to the people from the rescue party? Were they all killed outright, or were survivors sent straight in to the center of the Arena? If none of them ended up in the room with Samantha then how did she learn so much about how the zombies treat their prisoners? It seems like the only other case she would have seen is Martin's. And if the other survivors were put in with her and Kalani, and they're all gone now, where did she get the idea that prisoners were taken away in the order in which they were captured?
