Not fully over the end of season 2

I was truly disappointed at the death of Nat especially at the hands of Misty. Personally their dynamic was one of my favorites. I loved how devoted Misty was to Nat and how Nat was mildly annoyed and dismissed Misty. It didn't seem necessary to me to kill her off and I felt that it was almost thrown in there just for the sake of making something dramatic happen. I was really sad that Misty was the one to do it too. When she was walking toward the medical examiner's van she did not seem as distraught as I feel Misty would be either. Also when Nat said "I'm not supposed to be here" when she was in limbo, it felt like she knew something we did not, I was curious what the point was of that dialogue. Anyways, not my favorite part of the final episode. Thoughts?
