In that scene, Bryce tells Monty to leave him and Tyler Down alone. But in the next scene, Monty does the opposite. Why does he, for what feels like the first time, finally disobey Bryce?
Granaderos: Coming off that breakup, he has so much misplaced anger that he doesn't know how to properly deal with it. So he takes it out on someone he knows he can. He puts all his anger toward Tyler rather than deal with his own issues. The recurring theme with Monty is he doesn't know how to deal with anger and emotion so he lashes out.
How did you prepare for the bathroom scene with Tyler?
Granaderos: We knew it was going to be a heavy scene, so we wanted to tell it honestly and properly. I researched similar scenarios that have taken place in high schools, bullying and what makes a bully work the way they do, what goes on in the bully's mind. Sometimes set can be so busy and bustling, with people talking -- no discredit to them, but it's easier for me to zone out when I have music and less distractions. So I also made a playlist, very specific to the scene, the day, the character, and I just listened to that on repeat.
Do you remember what you put on the playlist?
Granaderos: It's a secret, but I do still have the playlist. For Monty, I found that the root of his aggression was pain. He has this pain because of the relationship he has with father; he has pain because of the break-off with his friend, Bryce; and he has pain because of potentially losing athletics. It's just so much pain and emotion that drives him to do something so horrific. In shooting that scene, it was such a blessing to have such nurturing and caring people, the cast, the crew -- everyone involved was so sensitive to the work that Devin [Druid, who plays Tyler] and I were just able to go in and do what we needed to do.
