ok a friend I have been watching the show together.
we've developed a little theory now that its been a couple days. i think it was when Bernard took Teresa downstairs and killed her there was a host being created with some older tech. we're thinking that the Ford (Hopkins) that was killed was just a host. and Ford was just creating a version of himself to 'die'. cuz when u think about it the host are on the brink of a breakthrough why wouldn't he want to witness it first hand and see his creations become 'alive'. I'm still not sure who let loose all the decommissioned hosts in the basement, if it was Ford, Dolores, or Mauve. But I'm guessing they'll be working for/with Dolores/Wyatt.
By the way I read somewhere that it's not coming back until 2018!!!!!!!!? WTH
