It's interesting that this preview already appears to reveal that this is another girl pretending to be Batgirl. After the last two issues you could still sorta hold up the theory that Babs may have developed some sort of split personality, but this preview shows both girls in the same frame. When i first saw the cover for this issue, i already felt like this girl in the sparkling golden outfit wasn't really Barbara Gordon because her face looks pretty different. It's an interesting fun mystery.
