All of season 4, don't read unless you've finished
I'm actually kind of disappointed with Netflix. I think they could've pushed the release date back a week or two. With the Orlando shooting just last week, I think it was just incredibly poor timing to release this season where one of the most beloved characters--an out lesbian--was killed. Poussey went through so much trout, and she was finally in a loving and healthy relationship with someone who loved her back, her future was looking extremely bright. It just sucks.
