The 'Westworld' Season Finale Just Dropped One Last Twist We Didn't See Coming

Sunday night's season 1 finale of Westworld was the perfect finish to a near-perfect season of television. While many fan theories came true tonight, there were some big twists that not everyone saw coming. Better still, the finale leaves plenty of loose ends flapping in the breeze, leaving the door wide open for a second season. Perhaps the biggest twist of the night was Dr. Ford's role in...well, everything. It turns out it wasn't Arnold's voice in the hosts' heads, nor was it Arnold manipulating the hosts to awaken and rebel.
