I just watched the very last episode and I am so goddamn confused. I loved the series, but I think there was so much left unexplained, and even some possible plot holes. Can someone just give me a brief explanation as to what went down in the second season? Maybe I missed something, but there seemed to be a lot of things that were left unanswered. Also, the time skip, what was the significance, and how long was it?
