Come on guys. You'll never know how Bruce went back to Gotham. You'll never know how he painted the bridge with oil. It doesn't make any sens because this movie is about making a legend, a mythe. Some stuff have to be mysterious. You have to imagine that stoy on your own!
That's the reason you can't talk about plot holes but you might name those "plot omissions" instead.
Here's an example.
There are set photos of Foley (Modine) holding pink panties, which he claimed were a prop when I talked to him. As the virals (as misdated some of them were) stated that Foley was the head of the Cat Burglar investigation, this tells me those panties were something Selina left behind. That's an assumption, I know, but there's an example.
Lol somebody put them in his coat pocket as a joke, it's got nothing to do with the film
