Re: Supes and Bats: how do they discover each other's identity (or do they?)
The idea of X-ray vision and a tracker seems kind of lame. I'd rather Bruce use some detective work and find out early. Then, someone else can be trying to uncover Superman and be having a hard time just to show how brilliant Bruce is.
I'd rather have Batman reveal himself to Superman later to show trust has been established. And then maybe Superman can respond with "I knew all along" or something and leave us wondering how.
