This episode was essential. I don't understand the amount of hates. One thing that we need to pay attention to is that this season we have 10 episodes. (Last season it was 9.) So if you're too sad that they wasted(!)one episode only on Cobel, (who is apparently a mastermind and a genius and a very important character whom we needed to know more about), you can imagine this episode never existed. Because I believe they added one extra episode just because they knew it's super important to pay attention to the importance of this character and think and feel deeper about her. It should be extremely hard to keep on creating a show with this high expectations from the audience... I agree that this ep wasn't as mind-blowing as the rest of them, but calm down y'all, it was still a masterpiece in it's own way. Specially the last 10 minutes!
