I am not of the thinking that the Ford that was shot in Season 1 was a host. Only because they showed his corpse a week after the event when the team went in, and there were maggots eating him. But I guess I do not know if Host corpses would attract maggots also.I think we're going to see a big turning point soon in regards to if this is Ford's game or not. If Ford is (or rather was) human, then his sanity is going to start to breakdown like we just saw with Delos Sr. Ford has about 30 days before his cognitive abilities will crash and he needs to be reset by someone in the lab. If Ford continues to challenge William/MiB after that deadline, then William is going to know that Ford wasn't human at the time of the uprising and his consciousness was constructed by someone else - possibly Bernard/Arnold?
I'm of the opinion that Ford is a decoy. We hear his voice in other hosts and just assume that it's Ford, but what if it's the "game master" just using Ford's voice through the other hosts. Ford's shift towards the end of S1 seemed very out of place from the younger version we saw in flashbacks - so what changed him?
Also -what if Ford himself was the safety protocols for the park? Only Dolores, who in my theory is the revenge vessel for Arnold, would have the programming power to kill Ford, as demonstrated when she killed Arnold. Ford either knows this as fact and he will either die of natural causes or at the hands of Dolores. Perhaps Ford finally saw what Arnold saw through what his park had become and said "you know what, you all deserve this" and let Dolores take her shot.
Ford could've certainly created the final cognitive control module for his eternal self, but I for some reason don't see him being a person who wanted to live for ever at the end of last season. I do think William admitting to Jim in last episode, that he has come to the realization that maybe eternal life isn't the answer, could play into Fords game, and that is why I was thinking he could potentailly be a host without knowing, and this game that he is playing is the game Ford programmed into that final cognitive control module Bernard made.
