What should we look forward to for tonight's episode and the rest of the new season? Warning: spoilers ahead!

According to Hypable, "NBC has released its promotional material for the second episode of Constantine, and we finally have our best look at Zed Martin yet. Trick or treat? We're certainly hoping for both as Constantine's second episode hits our screens on All Hallows' Eve. He's already showcased some trickery - those flames he manipulated at the end of the premiere made for an impressive display - but we can't help but want to be treated to some more of that wickedly naughty wit. Okay, we're done with the Halloween puns. We promise. The premiere threw us straight into the action, as it introduced the rich and dangerous world of Angels and Demons that Constantine has been navigating as a Master petty dabbler of the Dark Arts (he's getting new cards made). This week will see Angélica Celaya join the cast as Zed, the woman we caught a glimpse of at the end of the premiere, desperately sketching John Constantine's likeness over and over. The promotional stills for the episode show Constantine and Zed getting a little dirty, perhaps in pursuit of the demon through the mines? Whatever it is, it doesn't look like that stuff is going to wash out. Zed isn't about to let Constantine have all the fun, by the look of these videos - as John says, "She's as tough as they come." Though he doesn't initially seem to believe her intentions are honourable. Can't con the con artist?"

Care for some more S01E02 spoilers?

"The show's pilot was a success as it held its own against other highly rated programs that aired on that night, including the World Series. The premiere was also lauded by critics and according to Moviepilot's review. "Even if you have never read the comic or know of the Hellblazer himself this show will allow you to sit back and be both intrigued and creeped out," the site wrote. In earlier reports, it has been confirmed that show runners David S. Goyer and Daniel Cerone have decided to make a few adjustments in the show, particularly with the cast. Lead female character Liv (Lucy Griffiths) exited the show after the pilot, to be replaced by a character from the original "Constantine" comic books-Zed Martin. Zed, who will be played by Angelica Celaya, was introduced in the reworked version of the pilot episode, and shown drawing countless pictures of Constantine despite never having met him. In the comic books, Zed was one of the first allies and lovers of Constantine," explains CP Entertainment.
