Leaving a Mark

Leaving a Mark is the title of the third episode of American Vandal's second season which was first broadcast on September 14, 2018. The second season of the show follows Sam and Peter Maldonado's investigation into Turd Burglar and his crimes.

Plot
Peter and Sam head down to the basketball court in St. Bernardine to interview Tillman. It's revealed that DeMarcus is shown to be a generous person with an enthusiastic reputation among his peers and classmates and has special privileges and access to certain restricted areas – a reason that would give a motive to DeMarcus if he was the Turd Burglar.

Peter and Sam then look back into previous events, such as an incident in which someone stole the school mascot costume and posted himself in the costume on Instagram as "Sir Fux-a-lot" to sexually harass cheerleader Paige Burton. The culprit was Tillman's former friend, Perry Coleman, a former student and athlete. The story contrasts with Grayson Wentz, a student expelled from school for using school computers to post vulgar tweets on Twitter.

The duo deduces that St. Bernardine would nevertheless cover for athletes who have an enthusiastic contribution to the school at the cost of expelling outcasts, like Kevin and Wentz. Suddenly, Peter gets a surprising text from The Turd Burglar, telling him that he is doing "a shitty job" at finding him.
