Spoiler alert if you haven't watched last one
So I assumed as "it" was being done in the background, and they kept showing you the new host body being made that Ford is creating Teresa! Which explains why Bernard was studying her gestures and movements (remember when he coaches her about the defensive stance of crossing arms before her meeting with Ford?)
So is this the "secret" plan? Ability to kill important guests and replace them with hosts and send them back into the real world?
Also, Ford told Teresa the board already sent someone. Thinking about Ford's conversation with the man in black hat... I'm convinced that is the person the board sent, not the woman who is from the board. Ford didn't look phased by her at all while he did show respect for the man in black.
Anyone notice that Ford also prefers the company of hosts... He goes down for chats with the old cowboy, who is now obviously some sort of prototype, as you would your therapist. He said that's what happened to Arnold in the end when he lost himself...
Also not sure if anyone mentioned but if you google the two different logos theory - that supports the two timelines and I can't believe I missed it before! Definitely an older logo when white hat cowboy enters the park and when Bernard goes down to basement to access the old computer systems.
