The second episode of HBO's new sci-fi/western Westworld is now available on the network's streaming apps. This is ahead of schedule, as the episode was scheduled to arrive this Sunday, October 9 at 9 PM ET.

　　The episode is titled "Chestnut." According to EW, HBO might have released the episode early so as to avoid a clash with this Sunday's second presidential debate between Donald Trump and Hillary Clinton.
