"I barely know you! I've only been helping you out recently since the board meeting."
-Justin BrownJustin Brown is a major character in the third season of Quest 89.
Sometime before the events of the third season, Justin Brown fought in a war alongside Gunner and many other soldiers. Justin is the only known survivor. At some point after this, Justin Brown befriended the Professor, and went undercover as a police officer, dubbed Officer Brown, to cause chaos on Sodor.
Brown attended a meeting regarding the assassin where footage of him was shown stealing Toby. Brown offered to track the assassin down. Later, he set out with Thomas and searched for clues at Brendam Docks. When 089 became a runaway a bit later, Brown used an airboat to pick up Sir Stephen Topham Hatt and chase down the runaway train. Brown then surveyed the damage.
Brown attended a meeting at Knapford Station where Sir Stephen Topham Hatt adressed his engines regarding the assassin. Following the meeting, Brown mentioned that he lost his wife, but also that he arranged for BoCo to take him and Stephen to the Arlesburgh Pub. At the pub, Brown and Stephen bonded over how the assassin made their lives harder and Brown eventually convinced Stephen to have a snakebite. A drunk brown struggled to continue the conversation.
- Justin wears an old army helmet instead of a police hat. This hinted at General Phoenix Brown being related to him and his past in the army.
