Captain Knox is one of three police captains who conduct a disciplinary hearing for Officer Matt Parkman.
After the failed FBI raid on Primatech Paper Co., Matt Parkman returns home to Los Angeles, where he faces a disciplinary review for his actions. Initially, he files a truthful statement, detailing his belief that Mr. Bennet has Sylar in custody, but when he hears the captains' thoughts that they plan to write him off as crazy and kick him out of the department, he recants his statement and claims to have made the whole thing up. The captains suspend Matt for six months and request his badge and gun.
