Batman Issue 643

"Minor Discrepancies"
Batman swung down on Joker and the impostor Batman. He took down Joker, told Black to get lost, then went after the impostor. He finally caught up with his impostor, Black Mask. He escaped after gassing Batman. Back in the cave, Bruce found some problems with the medication inventory at Dr. Thompkins' clinic and what was (or wasn't) given to Stephanie. It appeared that she'd been neglected of her needed meds.

Rodriguez did a pre-interview with Stephanie Brown's mother; he planned on having her on his show the next day. He was appalled to find Aaron Black giving an interview on a competing channel about being attacked by two Batmen the previous night. He also implied that Rodriguez was in Black Mask's pocket. Batman went to the normal digs to get information on Black, Black Mask, Dr. Thompkins, and Joker. He left, acting overwhelmed, so his recorders could pick up conversations.
