The big flashback gives us a glimpse of Ford, courtesy of a digitally de-aged Hopkins, looking like his Elephant Man self, some half-built hosts, and a few familiar faces in the background of laboratory shots -- spot Peter Abernathy, loaded with Arnold's "bicameral mind" code that will eventually drive him off the deep end -- but no introduction to Arnold, making his role in the company, and his eventual demise, all the more mysterious. Ford reveals that he died in the park after a long stretch of reclusive behavior. "[Arnold's] personal life was marked with tragedy," he says. "He put all his life into work." By the end, he was only speaking to hosts. Arnold's death was marked an accident, but Ford doesn't buy it. "He was very, very careful."
Did Ford, wanting the spotlight and feeling threatened by the potential of robotic humanity, play a part in his partner's death? Or is he vengeful towards the robots, leaking an aggression built up over a lifetime of watching them get away with murder? Are the "reveries" a step towards the future of artificial intelligence or a step backwards to the past, when the robots were simpler and Arnold was still around? Ford does love to sit in the dank Delos Corporation basement and talk to Old Bill, a relic from another era. Whatever happened to Arnold, Ford still carries around with him as ammunition against his successors.
