When confronted with a potentially dangerous situation, Pete relies on his instincts and is willing to bend the rules if it means getting the job done.

In the pilot episode, Pete is living in Washington, D.C., working as a Secret Service agent to protect the president.

There he is given a job at Warehouse 13, along with Myka Bering, to protect and retrieve various powerful artifacts around the world, under the supervision of Artie Nielsen.

In the season 1 episode "Burnout" he is prepared to sacrifice his life to destroy a dangerous artifact that attaches itself to his spine.

Pete also goes to great lengths to protect his fellow agents if he believes they are being threatened — for example, his actions in the season 2 episode "Around the Bend."

Although Pete is a capable Warehouse agent, he has a childish side that he has never grown out of — for instance, seeing how many croissants he can shove into his mouth at once; a feat Myka describes as "actually kind of impressive when you see it.

In the season 4 premiere "A New Hope", Pete retrieves the missing part of Magellan's Astrolabe at the expense of his own life.

His partners and coworkers note that his natural empathy makes him approachable, which is why many of the people he interviews trust his sincerity and open up.

In the "Pilot" episode, he mentions that the first time he got a bad vibe was right before his father left for work the day he died.

This death led to his mother becoming increasingly active and so unavailable to Pete, who also lamented his sister leaving for college soon.

As revealed in season 2, episode 6, Pete once had a romantic affair with a fellow Secret Service Agent Kate Logan (Tia Carrere).

Pete's playful nature allows him to quickly develop a rapport with the teenage Claudia Donovan upon her arrival at Warehouse 13.

He admits to being in love with Kelly, is considering moving in with her, and is prepared to make her his "one," i.e., the one person with whom he is allowed to reveal the true nature of his work at Warehouse 13.

In season 2, episode 12, when Kelly falls under the influence of Lizzie Borden’s compact, because of Helena G. Wells, she tries to kill Pete with an ax before the artifact is neutralized in the nick of time.

Having come to Univille seeking a quiet and simple life, Kelly can't deal with the drama of what just transpired.

Despite their feelings for each other, Myka’s by-the-book approach and Pete’s off-the-cuff style often causes conflict between them; however, they’ve learned to appreciate each other’s strengths and work together exceptionally well as a team.
