JT Wicker is one of the officers working at GCPD in Batman: Arkham Knight. If you’ve seen him, you’ll know – he’s the one giving of a green glow.
You can talk to him, but he says nothing of interest. You can try to punch him, but it won’t work. You can scan him, but nothing will happen. What can you actually do with the glowing green cop?
Riddler Informant in GCPD
In reality, he’s a Riddler Informant. You treat him the same way you treated every other informant you’ve met – interrogate him. Walk up to him and press Triangle (Y on Xbox). You’ll get to see a funny cutscene, lock him up and he’ll reveal a couple of Bleake Island Riddles for you. If you ignore him, nothing bad will happen, except for the fact that there’ll be another criminal walking freely.
