Well yeah, obviously the hosts were going to do some killing. I expected Maeve's thing, it was the apparent slaughter at the end that I feel will totally change the character and feel of the show.
I mean, after Maeve's near escape, I could see the park getting cleaned up, she is caught and decommissioned or wiped, and things go "back to normal" until some other incidents occur. But after the end of the episode... no way. Once news gets out, they will send in the marines, nuke the park, and it's all over. That is the way things look to me anyway. I'm sure there will be something to make it a bit more complex, like "oh, nobody outside knows hat happened", but just with so many humans at the final party, all big names in Delos, it should be obvious what went down when communications cease.
Seeing "newbies" in the park figuring out how it all works was incredibly fun for me, and I don't see how they can do more episodes like that in s2 unless they are flashbacks to before the massacre.
Maybe I'm wrong, I'd love to be pleasantly surprised.
