Re: Which female character shared a deeper connection w/ Bruce?
As someone who knew Bruce from childhood and knew him before and after his parents were killed, Rachel definitely understood Bruce. The difference is Selina and Bruce could identify with one another, which is the key. There's a mutual respect there, they're both warriors. Rachel and Bruce had more of a deep friendship that had potential to be more. Selina and Bruce had that flirty, kinetic kind of thing going on because their personalities were like bread and butter.
I don't think Rachel is his one true love, I think it's the love that could never be because of the choice he made to be Batman. Selina is his one true love in a post-Batman world.
