Pyromaniac, or pyro, defintion:

Desire to burn things: the uncontrollable urge to set fire to things

Bronson pulled his gun out, which when shot, emits mini-flames — hence pyro — due to the fact that pyros are obsessed with fire.

Also, since Action shot someone in the foot — hence, “Put the flame to his sneakers,” — a gunshot wound would have a burning feeling; Just like how a fire would burn someone.

An inquisition is a interrogation that is usually very aggressive, violent, and usually involves the use of torture. Meyham would refuse to answer to interrogator’s questions in an inquisition despite the types of tortures he’d go through because he never snitches, while most people would snitch right away because they’re afraid of being tortured.

Today the use of “simulated drowning” is performed during inquisitions. Simulated drowning is when buckets of water are continuously poured over someone’s head to make them feel like they’re drowning.

An infection is a disease that can be spread between people, and an incision is a deep cut of the skin, coming from his knife in this case.
