This whole thing with kidnapping Mia made no sense, but damn if I didn't enjoy it. :)
I always kept wondering what kind of conversation Jason would have had with Cass, if she had stuck around Gotham City as Batgirl. Since Cass's parents were both criminals, but she's still fighting the "good" fight. I can't help but imagine Jason looking at Cass, shaking his head and thinking..."What is up with that?" Where does she fit in his world of logic?
