Gordon and another Non-Bat Hero
Found one more (very brief) example of Gordon and Non-Bat Hero Interaction (Also, includes Bat Hero)
Aaaaaaaaand that's the extent of their interaction.
Plus a one-page Jim Gordon Mystery:Whodunit! For You to solve. If you can!* (Warning: Stop after the second row if you want to try:)
*I couldn't, but I didn't really try. My eyes went straight to the lady's "WHAAA?" panel.
