I just closely rewatched the trailer. Things I noticed: sexy Jimmi Simpson William in a black suit with Dolores, what LOOKS like her talking to a young William and threatening him (but I don't think that's right, I think that's a red herring, as Teddy is with her and she's in her battle outfit), the Ghost Nation picking up Logan after William sent him off, Ford's mini-me clearly dead, not just Dolores escaping the park, but Teddy too (dressed as a security guard? cop?). I think the conversation playing over with her and Arnold is meant as a misdirection, as it plays over what's happening with Bernard. I think Elsie is the only one who knew Bernard is a host (I assume, if he killed her or just incapacitated her), but it seems like Stubbs trusts him. He might be working on the inside, but he might also be a double agent, as he didn't suffer the same way at the hands of the humans, and had relationships with them.

ugh 12 days
