Prediction: Arnold Is Alive How about this - Arnold is alive.  The "Arnold" that Ford thought died was a host that Arnold had created as a decoy so that could (for whatever reason) fake his own death and go into hiding in the park.  Thinking that Arnold had died (or maybe that he had killed Arnold), Ford then created another host of Arnold--BernArnold, which is the one we see meandering about the park. Meanwhile, the real Arnold is the dude who is reprogramming the hosts and the dude who grabbed Elsie from behind in the haunted house scene.

Thoughts?
