Westworld: 9 Mysteries That Season 2 Must Resolve 

9. Who Is Really Self-Aware?

Delores? Maeve? Teddy? Hector? Are they alive, or following their code?

One of the most entertaining and engaging mysteries of the first season of Westworld was determining who was actually becoming aware, and who was simply following their loop - or a modified loop.

It's safe to say that by season's end, three hosts are fully aware, and arguably sentient beings: Delores, Maeve, and Bernard. The waters are muddied a little by the fact that all of them have flirted with awareness before (Bernard specifically states that this is not the first time he has "woken up"), but in the end, they're safe bets.

What of Teddy, though? Is he following his loop, and saving the day, or has he really woken up? How about Hector, who after all, doesn't seem to have evolved from the shortsighted, shoot 'em all gunslinger he was programmed to be? Was Clementine waking up, given she was suffering from troubling dreams, prior to undergoing the android version of a lobotomy?

This is one mystery the show needs to clear up in the second season. While the "who is/who isn't" question has been fun, after a while, it could become tedious. By mid-season or so, all - or at least most - of the chess pieces should be on the board.
