Interesting indeed. I personally thought the adventure was great, and I don't believe that the hidden Batman references would even come up during the adventure, unless one of your players is some kind of freak anagram mastermind. Which is what I'm looking for! Finding anagrams makes me suspicious of every name I see!
Here's what I found or gleamed from other sources
Meridian Chase (Batman's love interest from Batman Forever)
And thats all I've found so far, but I know theres more. I feel it me bones!
