Now that they knew the location of her group, there was a decision to make. They could let her join the group, lock her up, or kill her. The first one would probably be the worst option. She could betray them at any moment. The second option was risky. They would probably need more information in the future, and when they do, she might be able to give them answers. If she escaped, though, it would end badly. Then there was the third option. If they killed her, there was absolutely no risk. She wouldn't be able to go back and tell her group where they've set up, but if they needed more information they would have no way to get it. Plus, they would have even more blood on their hands.

Deravan seemed to be trying to "fix" the wolf, which didn't seem possible. Connor, on the other hand, was intent on killing her.
"She can't be reasoned with, Deravan." Ralph said. "I still don't think we should kill her, though. It's just not the right thing to do. Besides, if we ever need more information about this group, where else are we going to find it?" He turned to face everyone in the group. "I've made my decision. I vote to lock her up."
