The Second Part. An interesting fact about this episode, if you pause it exactly halfway through, you will also be paused halfway through the series. spooky eh. Part 2 comes after Part 1 - and - before Part 3. Even though this is Metal, the groundbreaking genre, they decided that this was a tradition they wouldn't break. Part 2 is notable in that after you watch Part 1, this was voted the most likely part to watch next. Take that as you will. I think it's a global conspiracy sponsored by big pharma and the Illuminati, but I might be wrong (I'm not!!).
