[Shortly after
this...]
There is a slim, serious woman sitting at a booth. Her posture is a bit stiff, but it's the stiffness of someone who's very uptight. Her red silk suit is impeccably pressed and her gold-rimmed glasses are secured by a delicate chain of the same metal which hangs around her neck.
The only thing to spoil the image of an uptight, up-and-coming business woman is the large strawberry milkshake in front of her. Though her occasional sip of said beverage is admirably restrained.
Anyway, it is completely understandable that most people won't recognize this young woman as Cassandra Cain. Or as Batgirl. Neither of whom are known for their business suits or restrained manners.
