Synopsis for "Batgirl"
Cassandra Cain and Barbara Gordon are training with fight sticks and the new Batgirl is impressed by Oracle's skills despite her sitting in a wheelchair. Having finished the workout, Oracle continues to research what David Cain did to Cassandra besides raising her into a master assassin and severely limiting her vocabulary so that she is able to read body motion in place of language as a combat technique. Its tough for Oracle not to be able to talk to Cassandra and watching her having nightmares while sleeping. But Batman is trusting that Cassandra is able to handle that as well as being Batgirl. Batman allows Batgirl reign of Gotham city, but with the proviso not to confront any costumed criminals.
