The ending to the show absolutely ruined the entire season for me. It felt like a cop-out and just plain lazy writing. Memory loss, in my opinion, is the worst thing for a show to do and usually signifies that the creators are out of ideas and want to repeat previous material. Even if that is not what happened in this situation, instead you totally betray all the work you put into a main charecter. All season it is reinforced that Alyssa is someone who believes everyone can be redeemed, than you have her go and betray the one person she is closest to? It is not something that her charecter would have done. It doesn't make sense and completely ruined what I found to be an enjoyable season.
