The most interesting about this episode is the final shot in which Aaron is "teleported" back in time (before the blackout). Well, who really knows. It could be the entire series takes place in the past and he woke up from a "dream" and is remembering what will happen in the future. Or, everything does in fact take place in the future (where the story has been riding for 2 seasons) and is indeed transported back in time. Either way, he does remember the nano tech. Very interesting. The third option would be that the Nano is f*cking with his head for trying to shut down and kill the AI. Beyond that, this was just an okay episode for me. Even having Charlie "dressed to kill" was kind of weak. For whatever reason, they don't want to put her in anything remotely sexy, even if the scene calls for it.
