He's terrified of the dark, but the cause is unknown.
He suffered Post Traumatic Stress Disorder (PTSD) in the third season, but seems to have recovered.
He loves watching programs about wild animals, the likes of which you'd find on the Discovery Channel or Animal Planet. He tends to side with the prey over the predator.
When he was a child, he used to stand up to bullies that picked on a skinny kid in his class, just to 'even things up' a little.
He's been sent to compassion therapy many times.
He doesn't get along with typewriters so it's probably a good thing he seems to let Faith write up most of their reports. If Faith is to be believed, he also tends to have a lot of spelling errors.
He likes to do something called the "Waffle" in which he slams on the brakes of the RMP when a perp is being annoying, sending him or her hurtling face-first into the metal grid barrier.
