Josh is socially awkward, mostly quiet, has little to say, and doesn't seem as emotionally expressive as other team members. He also doesn't understand certain slang words until they are explained to him, such as the term “cornhole.” However, he does have a sense of humor similar to that of his fellow DedSec members, often making quieter jokes during scenes with them. Josh himself hints at having Asperger's syndrome in an episode called "Carnival Chaos" from the game "Mirrorverse," later confirming it in the mission DLC "Caustic Progress." This is also mentioned in Horatio’s report on Josh, where he's described as having high-functioning autism. The actor who voices Josh, Jonathan Dubovsky, also revealed in an interview that his character has Asperger's syndrome.
