That's exactly what happens. Apparently Diana told Cassie not to join, because she was not ready to be part of a team (training Blah, Blah!!!!) Of cource exception was taken and it was on. In a very big way. It was actually pretty funny, mostly it was mentors versus students. The most hunourous thing in this book was actually on the cover. In the lower left hand corner, we have Batman trying to scare Tim Drake "BOOOO!!!!" Story was ok, but it could have at lewast lasted three more pages, art was spectacular!
