I guess Aaron thinks he knows what's going on with his "revival"? Looks like what happened in the 6 months after the power went off again is going to be revealed in little, short flashbacks. What made the computers crash? Looks like whatever Aaron was doing has turned off The Tower's power as well. What's going on with Charlie and Monroe? And, we can't complain this season about how clean and tidy everyone is, now can we? Discussion?
