The trigger warnings at the start of the last few episodes were greatly appreciated. That being said, this is also really helpful if you want to know specifically what troubling things are in the show:
There are also a few scenes that involve guns. One is in the very last episode, and the other is a few episodes before it. Sadly, I don't remember exactly which episode off the top of my head. It's the scene with Bryce and Jessica. If you've watched the show, then you know which scene I'm referring to.
