Yeah, it kind of is the only one where she stars. I say stars because Bruces goes batshit for most of the story, and ends up living in a hole in the ground and eating worms, so Cass is left the carry the story until he gets over it.

Cass IS kinda awesome in the story, though she sort of talks too much (this was just after Officer Down, so she wasn't into monologues yet) and the only mention of her dyslexia comes in an off-hand comment when she gets Alfred to read some computer files for her.
