Warning: This article contains spoilers for 13 Reasons Why season two. 13 Reasons Why has been hit with controversy since it first aired last year on Netflix. The drama, about a teenage suicide, has defended itself numerous times over its graphic content - but it has now gained more attention over another scene. Season two features a male-on-male sexual assault where Tyler Down (Devin Druid) is attacked and violated in a toilet with a broken mop. The traumatic scene sheds light on his mental health which then drives him to plan a mass school shooting. But now, the Parents Television Council (PTC) have called for the show to be cancelled after the difficult scene.

The US group has targeted shows such as The Walking Dead and Scandal before for its airing of “extreme violence” and has now demanded to have the 13 Reasons Why scene reviewed by their experts. In an open letter on their website, the group describes their warning to parents and schools as “urgent”. The PTV president, Tim Winter, says: “Netflix has delivered a ticking time bomb to teens and children who watch 13 Reasons Why. “The content and thematic elements of the second season are even worse than we expected. “We would have liked to have 13 reasons for hope and redemption following the graphic suicide of the lead female teen character, but rather than providing a path forward, the season only provides cause for despondency.”

PTV programme director, Melissa Henson, added how the show acts as a “trigger” for children with mental health issues and has urged parents and schools to “be on guard” in the coming weeks. A Netflix spokesperson told Express.co.uk: "Sexual assault is vastly underreported; male on male sexual assault even more so. Assaults, such as Tyler’s experience, occur but are often not discussed. 13 Reasons Why takes on difficult topics that are too often surrounded by silence, and gets people talking about them in a constructive way - as shown in recent research by Northwestern University. We know the subject matter can be difficult to watch. That is why we have ensured we have the warnings, tools and resources in place to help anyone affected by the content in the show. This can be found at www.13reasonswhy.info. "The Tyler storyline was, and is, intended in this particular case to highlight the experiences and mindset of one fictional character who comes close to committing such an act. This story does not serve to glamourise or excuse any act of violence or disrespect anyone who may be touched by such events." 13 Reasons Why’s second season opened with a warning from the stars of the show. They explain how the mature themes may not be suitable for everyone and may need parental guidance. The creator of the show, Brian Yorkey, has defended the scene during an interview with Vulture.
