Growing Suspicion

Growing Suspicion is the fourth episode of Season 1 American Vandal.

Synopsis
Peter takes a closer look at the "Morning Show Nine," a group of students -- including Peter and Sam -- who had access to the missing security footage.

Plot
Intent on narrowing down his list of suspects, Peter constructs a theory concerning the Morning Show, the daily Hanover school show that Peter, Sam, and Dylan are part of the crew for. He makes a statement that one of the nine members of the school show's crew, including senior school president Christa Carlyle, might have something to do with the phallic incident.

Peter digs deep into every member's motives and alibis until he finally gets to Sam, whom Peter theorizes to have drawn the penises on the cars to get Gabi's attention. However, these assumptions frustrate a confused Sam, who angrily steps out and scolds Peter for being too easy on Dylan, the investigation's primary suspect. Then, Peter theorizes that Dylan could have drawn the penises to get Mackenzie's attention due to a breakup that happened three days prior to the phallic incident. However, Dylan continues to state his innocence in the face of Peter's new assumptions, leaving Peter in the cold, until he eventually gets a call from Janson's daughter concerning a "Kiefer Sutherland-type" voicemail.
