|First Appearance:||Batman: Arkham Knight|
At some point before the events of Scarecrow's threat to Gotham City, Medic Bailie as well as three other people were abducted by Lazlo Valentin, better known as Professor Pyg, and brought to Gotham City as part of the deranged doctor's Dollotron experiments. However, Pyg never got the chance to experiment on them, as Batman proceeded to confront and beat Pyg, having deduced his role in six abductions and murders of people outside Gotham, with Batman also releasing them from their cages. Bailie upon being released had collapsed to his knees due to the traumatic events weighing heavily on him, and expressed relief that Batman arrived at the time he did, expressing enough horror at what Pyg did to the others that he simply couldn't finish what he was about to say. They were then presumably taken in by the GCPD and given shelter. Bailie likewise had severe mental trauma from having to watch Professor Pyg conduct his experiments on several people, severe enough that even his briefly falling asleep had him replaying the events of his abduction, including the screams and witnessing the surgeries.
- Medic Bailie, alongside the other civilians rescued, are never actually named after they are released from their cages, just being given the name "civilian" during dialogue. It is only by talking to them after placing Professor Pyg in the lockup that their names are identified.
