I enjoy that the minute people get confused about a plot it means the writing is bad.
"Clever things make people feel stupid, and unexpected things make them feel scared."
-Philip J. Fry
Not gonna lie, I thought this was going to be a case of suicide framed as murder. If you go back and look at everyone's face, none of them had the face of someone who was struggling with an attacker or being attacked. They all looked... resigned. As if they accepted their death.
