Spoiler alert. I realize that there aren't that many of these left to give. I'm starting to get a little emotional thinking about how this is one of my last spoiler warnings. This show has really gone by in a blink. It seems like only yesterday I was reviewing season seven, and now we're on the final run of episodes. But that won't stop me from my duty of warning you that there are spoilers beyond this point, so think twice before proceeding. I'd hate for you to get depressed and go an an epic binge and then vow never to do that again. It won't be pretty.
