It should be noted that the pilot shows shades of his nicer traits such as: using his ability to figure out the positive Character Depth of the girl he has a crush on, feeling guilty when he thinks his psychic act may have led to murder, trying to stop a police officer from listening to another fake psychic, and both young and adult Shawn referring to older women and authority figures as "ma'am."
In earlier episodes he would immediately rule out any supernatural phenomena usually dragging Gus back down to earth, yet later on, most notably in "This Episode Sucks", he is perfectly accepting of the culprit being a vampire.
The Charmer: Shawn's greatest asset (excepting his attention to detail) is his ability to charm people, which is odd since he also has a singular talent for being tactless and irritating.
Distressed Dude: In ''Shawn Takes a Shot in the Dark, and in any situation where he confronts the murderer or gets caught without backup. It's usually Jules bailing him out.
Dude, Where's My Respect?: Shawn's unorthodox methods have been the deciding factor in arresting murderers, thieves, con artists, and even serial killers. Many times over the course of the series the Santa Barbara police would have imprisoned the wrong person, and many people would be dead, without Shawn's help. Despite this, every week the cops (mostly Lassiter, really) say they don't have time for his "hunches," his help is not needed, and please get out of the way so the "real" cops can do their jobs.
Expansion Pack Past: Shawn, in partial rebellion to his father, has had fifty-seven prior jobs and has spent time in Argentina and Thailand among many other places.
Photographic Memory: He was able to look back on something that happened while he was in elementary school and remember a new detail that he'd missed before. This is standard procedure for him gaining evidence.
Screw the Rules, I'm Doing What's Right!: Partly why he goes above and beyond police protocol when he thinks the wrong person is being prosecuted. Not that Shawn has a problem bending the rules in the first case.
Took a Level in Dumbass: Makes some really stupid mistakes in later seasons, as explained by Henry as not being challenged enough by the work that he does and getting sloppy. He cleans up his act.
Training from Hell: A watered down version to be sure, but Shawn's father Henry relentlessly drilled Shawn from very early in his childhood (to the exclusion of a normal childhood, save Gus ó which isn't saying much) to have the uncanny attention to detail and eidetic memory which now allows Shawn to convincingly fake having psychic abilities.
Vitriolic Best Buds: He and Lassiter may snipe at eachother alot, but when push comes to shove they do respect eachother and are willing to rely on eachother if they're forced to.
"Well Done, Son!" Guy: Henry isn't the easiest guy to impress and doesn't exactly conceal when he's disappointed, meaning that Shawn has spent most of his life either trying to impress his father or actively rebelling against him.
Wouldn't Hit a Girl: He doesn't really have to hit anyone most of the time, but whenever the culprit is female and he's pushed to it, he makes specific mention of this.
Worthy Opponent: To many criminals, but Desperaux calls him this. Yin calls him his "most admirable foe."
Burton "Gus" Guster (Dule Hill (Adult); Carlos McCullers II (Child))
Retirony: As of the season six finale. Subverted, he survives it.
The Scapegoat: Henry took the blame for his divorce so Shawn wouldn't resent his mother.
Sink-or-Swim Mentor: To teach his son to escape a locked trunk, he actually locked him in a trunk. Somewhat justified as Henry's police work made him Properly Paranoid about the dangers a young boy could get into.
Detective Carlton Lassiter (Timothy Omundson)
Adorkable: He had some moments that could be called this before, but any moment he's on screen with Marlowe makes it unquestionable.
Crazy-Prepared: He keeps guns everywhere in his house, including in a bowl of almonds. And that's just the start.
Foot Dragging Divorcee: Lassiter was in denial about his separation from his wife, and thought they were getting back together when she asked for dinner at their first-date restaurant. She confronted him with divorce papers and he gave a long, foot-dragging speech, but eventually admits he was aware he'd never been good for her. Having gotten that off his chest, he immediately signs the papers.
No Social Skills: He once gave Jules a friendly speech about how other people were only sources of misery to be avoided at all costs-and he meant every word of it, thinking it would actually help her.
Took a Level in Badass: In season 1, Shawn needed to set up Lassiter solving a case to boost his confidence. By season 5, he's had many notable moments of awesome and can outpace Shawn for the majority of an episode.
Trigger Happy: So much so that the department eventually had to send him to a psychiatrist.
Vitriolic Best Buds: He and Shawn may snipe at eachother alot, but when push comes to shove they do respect eachother and are willing to rely on eachother if they're forced to.
Screaming Birth: Averted, when she gives birth over the course of several hours, without screaming, on a properly angled table.
Secret Secret Keeper: It's been implied a few times she may know more than she lets on, and just doesn't say anything so Shawn's cases won't get thrown out.
Officer Buzz McNab (Sage Brocklebank)
Fair Cop: In "Deez Nups", it was revealed that Mc Nab is working as a stripper at a hotel so he can have extra money to buy himself and his wife a new condo. In No Trout About It, interim SBPD Chief Harris Trout fired Mc Nab after he heard about his job as a stripper.
Meaningful Name: Debatable whether heís lived up to it or not, but one has to wonder about a cop named McNab
