Cassandra isn't good at talking, but she's real good at whoopin'.
The Spoilers:A couple of things happen this issue, Shiva locks up Batman's team under a nuclear bomb that's going to destroy the cave system Gotham is built on, thus causing the city to implode on itself, and while that happens, Cassandra is waking up to her hidden home on top of the ballet, where the dancer she was watching has found her.
Cassandra wakes up to the dancer reading her a story about a girl who was a shadow, and through some light discussion, Cassandra gets the confidence boost she needs and sets out on her own as Cassandra Cain, not Orphan, not the daughter of Lady Shiva, she's intent on deciding her own fate.
And she does that by storming the League of Shadows' lair, while the Colony potentially plans to use what is essentially smart napalm to burn the League out of their nest.
Cassandra makes her way to Shiva, who remains unimpressed, but Cassandra calls her bluff. Having freed Batman and the rest of her team, Cassandra and her allies make their stand.
