Constantine's 13-episode first season comes to a close on Friday, February 13th (how apropos!) with "Waiting for the Man." John and Zed travel back to New Orleans to help out a case involving a missing girl while Papa Midnite makes a deal with some dark, mysterious forces that could spell out huge trouble for our hero.

I spoke to series star Matt Ryan about the big season ender, the return of Emmett Scanlan as DC's Jim Corrigan, John's relationship with Zed, the future of the show (and whether it could possibly wind up moving to Syfy) and more.

Well, obviously it's the season finale. That goes without saying. So it's big. [laughs] But it's actually a story that's taken directly from the comics. And I think throughout the season when we've adapted things straight from the comics it's been very well-received. And so we've enjoyed that very much. But you'll also see the return of Jim Corrigan and Papa Midnite. And it's interesting because this time we see a development in John and Jim's relationship. The last time we saw Corrigan he was mostly paired up with Zed. This time he's actually asked for John's help and we see things progress in their relationship. We also see Jim taking a step toward what he's ultimately going to be - which is The Spectre. Which is great stuff.Papa Midnite also comes back to exact his revenge on John. There's a hit out on John. A bounty. Someone's placed a hit on him and we don't know who it is. We also reveal a little bit more about Manny and his character and backstory. So that's really interesting too.I don't think so really, to be honest with you. When I said they were well-received, I think it's more that those fans out there know those stories and they see what we're doing with them and how we're actually using them to showcase what the show's all about. And they're happy with that. For me, I think all the stories are great. I love the comics, so when we're doing something that's lifted directly from the comics, it's always really exciting to see what the writers do with it and how we wind up adapting it. So yes, it is always exciting. But then again the other stories are new stories and they're just as exciting for me as well.Well, with that one... You'll just have to wait and see. [laughs]. I mean truthfully, there's not much I can say for that. There's only so much I can reveal, obviously. I think Corrigan being in this episode is good though. He was sort of a reluctant participant in the last episode he was in, but this time he's actually asking John and Zed for their help and doesn't have to be introduced to their world anymore. And, like I said, he takes a certain step toward becoming The Spectre. There's a psychological, mental switch that gets flipped for him, so look out for that.Yeah, it's so much fun. I mean Michael [James Shaw] is just great and we have a blast together. It's always fun playing those types of relationships and with those types of dynamics. I really enjoy them. And Michael does was well. He's this huge guy who's so overpowering, but then John just doesn't give a s*** so it's great. He's just always like "Yeah, whatever. Piss off." I find it really really funny. Because when you look at the two of them Papa Midnite looks like he could take John out with one punch, but John just keeps giving him all this s***. It's a really fun relationship.I think that he's a master at disguising his emotions. And that's what's really fun about playing him. Looking at what level, on a scale from one to ten, is his actual fear factor at. And then deciding how much of it he would be hiding from the others. But he is a human being at the end of the day, and that's what I love about the character so much. He isn't the quintessential superhero who comes from another planet and flies around with a cape. He's a human being who has human problems. And has psychological problems just like everyone else. He's just street-wise and world-weary and knows how to not show anyone what he's feeling.I think it'll do both. I think it will and should do both. Hopefully it'll reveal a few things to the audience that we've been setting up throughout the season, but also give some enthusiasm for the show possibly going forward if we get picked up and are given another season.I don't know for sure, but there's been some talk. I mean we're always talking and I always talk to Daniel [Cerone] and David [Goyer] about what else we could adapt from the comic books. One storyline I'd love to see in there is "The Family Man" storyline. That's something that we could do if we came back for a second season. That's not to say that that story's in the cards, by the way, because obviously that's their job and my job is to play the part. But there are so many great storylines that I'd love to explore and I think this show has huge potential for many seasons to come given the great source material we have.I think that if we get a second season, we'll get see what happened at Newcastle. I think we will.I think John at the beginning was someone who was reluctant to take anyone new under his wing, so to speak. But then he saw what was useful about Zed when it came to the fight against the Rising Darkness. But there was also a part of him that wanted to keep her at arm's length. The two of them spent a lot of time trying to figure out each other's histories and backstories. Who they really were and where they came from. But I think over the course of the season they have become attached. And in the last episode you did see John get shaken by the news of her having a tumor. And it goes to show again his human quality and that no matter how hard you try to keep your distance from someone, if you spend enough time with someone you start to build a relationship and inevitably you become attached. And it comes back around to everyone who's around John winds up dying. But I think there's still a lot more places we can go with that relationship. Obviously in the comics they get together. We haven't explored that on the show yet, but there's chemistry between them. So it would be interesting to see what we do with the two of them going forward.Heh, I heard that news when you heard it, man. [Laughs] I was like "Oh, really? Is that something that could happen?" I mean, hopefully, that would be cool if it means that we get to continue exploring this world with these great characters and great stories. But I know just as much as you do right now. But fingers crossed.
