Yes, That Was a Cover of Nirvana’s ‘Heart-Shaped Box’ in ‘Westworld’ Season 2 Trailer (Listen)

Dolores' got a gun -- or at least some bullets

Oh, look, it's Dolores (Evan Rachel Wood) with a bullet belt. That's new and different. Probably meant to make her look like the most badass host in Sweetwater, as she leads the uprising that was started when she shot and killed Dr. Ford (Anthony Hopkins) at the end of Season 1. It's working.

The new guy

In this shot, Antoine Costa (Fares Fares), is seen at a makeshift campsite. He's a new character, a tech expert brought in to try to restore order for Delos Destinations amid the chaos of the robot uprising.

Whose side are you on?

And at that same makeshift camp is Bernard (Jeffrey Wright), your favorite host -- next to Dolores, of course -- who didn't actually know he was a host until well into Season 1. He appears to be cooperating with the group here, so does that mean he is on Team Human in all this? He did work for the park until he discovered the true nature of his reality, so it's a possibility.

Yup, definitely Team Human

Here's more proof that Bernard is siding with the non-AI crew in this war, as we see him with Stubbs (Luke Hemsworth) -- yup, he's alive -- and some "Westworld" newcomers, control team members Karl Strand (Gustaf Skarsgard) and Maling (Betty Gabriel).

Bernard, you traitor

Here is yet another picture showing Bernard in cahoots with Delos, as he appears to be consulting with Charlotte Hale (Tessa Thompson), Delos' executive director of the board overseeing Westworld, who was working to oust Ford -- till Dolores took care of that little problem for her. Of course she started a whole other problem then too.

New look, who dis?

Now here is a pic of new series regular Talulah Riley, in a very different mode than we're used to seeing this host. In Season 1, she played the greeter Angela who welcomed William (Jimmi Simpson) to the park all dressed in white. She was later discovered by Teddy (James Marsden) and The Man in Black (Ed Harris) as a prisoner. Here she is looking pretty seductive. No clue.

The other leader of the pack

While Dolores spent the entire first season traveling through her own maze to become self-aware and ultimately start the robopocalypse, Maeve (Thandie Newton) came to that realization as well, albeit with a little manipulation to her programming at first. But come the finale, she went off track and decided to go in search of her daughter inside the park, rather than continue on her set path to escape Westworld. In this pic, it appears she's taking charge, just like Dolores. Wonder if they are working together, or there are multiple factions inside Team Host. Gah, we already need to get out a white board.

Where the hell are we?

This season, creators Jonathan Nolan and Lisa Joy have said we are definitely going to travel outside of Sweetwater, and Westworld itself. We just didn't know one of those new locations would be so blindingly bathed in red light. Oh and there it's Lee Sizemore (Simon Quarterman). Looks like he's still alive and working with (for?) Maeve.

Back in black

Ed Harris is returning as the Man in Black. All you need to know here at the moment is that the park's most loyal customer clearly survived the fight that ensued between the hosts and employees at the end of Season 1 when Ford was shot (but did you really think he wouldn't?) and is still playing the game.

Hanging tough

Hector (Rodrigo Santoro) is also looking pretty good after going through a rough shoot out with Delos employees to help fellow host Maeve try and escape at the end of Season 1. Of course, she wouldn't let him come with her and ultimately decided not to leave herself. That may not lead to a happy reunion in Season 2.

We'll see what all this really means (or doesn't) when Season 2 of "Westworld" premieres on April 22 on HBO.
