Well, roll me over and fuck me sideways. Best episodes of the series so far. Hands down. That final five minutes opened up so many possibilities. Who knows how many people on the inside Ford has doing his bidding.

"

What’s more, it reserves the right to use this property in any way, shape, or form in which the entity sees fit.”
If I were a betting man, I would say that Ford got saliva or vaginal juices from Theresa off of Bernard after one of their sexual encounters. That host that was printing in Ford's basement lab after Bernard killed Theresa is going to be a copy of Theresa. She'll go back to doing her thing and no one that works at or for Westworld will notice. Ford said he needed a blood sacrifice. He's probably going to use real Theresa's blood in the host so she can still pass any kind of biometric security Westworld is likely to have. And Bernard made a comment a few episodes back to Theresa about the specific ways her faced moved when she was angry and trying not to show it. Ford is getting info on every little nuance she has in preparation for her replacement.
Also, Hector being a sex slave to humans overseeing Westworld is an awesome way to hear all kinds of 'closed door' conversations, just like the one we saw. Fucking genius.
One thing I'm still a little confused on, why do the workers sometimes wear suits when entering the world and sometimes not? When they froze the park mid-day in the most recent episode, the employees were dressed head to toe in those suits when they removed Clementine. Also, just occurred to me that just prior to that, she said something like "get out of the desert and go some place cold". My guess is cold storage isn't what she had in mind. And to piggyback this scene a bit, Mauve didn't freeze when all the other hosts did. Strange.
