I'm left wondering when exactly she was put in the barn. It had to have been after Carl was shot and obviously before Shane hobbled Otis. So when exactly and why? Did Otis feel like it was retribution for shooting Carl? That's assuming he truly thought the Zeds could be cured of course.
Weird twist. Even though I expected it, I kept hoping they'd find her alive. Thought I knew really she didn't have very good odds at all given the period of time she was "missing".
