Thankfully I watched last night's episode before reading the above comments as people seem to be neglecting spoiler tag etiquette in this thread. :tsk:
At any rate, great episode! I normally don't get nightmares from watching scary movies/TV shows, but I had a couple of dreams last night about the world getting zombified, including one in which during an LA Lakers/LA Clippers game, the players started turning into zombies on the court while playing, and it was all the coaches for both teams could do to replace them with still-human players, because, well, the zombie-players weren't exactly good team players. Blake Griffin, however, made for a pretty badass-looking zombie.
