Sam and Dean Winchester are raising a little hell in Supernatural’s 13th season. Or, perhaps more accurately, a little hellion.

The season 12 finale culminated with the birth of Lucifer’s son, Jack. Unfortunately, the newborn’s mother, Kelly Kline, perished during labor. Seconds later, Sam discovered a fully-grown adolescent male huddled in a corner, sporting a devilish smile and glowing eyes.

Concerned Jack could potentially become one of the most powerful beings in the universe, Sam and Dean have taken him under their wing to teach him about humanity and how to control his emerging abilities. It’s been a rough and confusing road for Jack, and his toughest lesson transpires in Thursday's episode, "Tombstone." It’s one that could permanently push him away from the Winchesters forever.

During SYFY WIRE's recent visit to the Supernatural set in Vancouver, actor Alexander Calvert spoke to the press about Jack’s reunion with his surrogate father, Castiel, the heartbreaking lesson he learns, Jack going solo and the joy of filming a Western episode.

What was it like filming the big Western episode?

Really fun. When I read the script, the first thing I did was talked to costumes. I was like, "What are you guys wearing?" The costumes are really fun. You get to see Sam and Dean, especially Dean, be in his own element, so it was a really fun episode from that kind of cowboy, Western standpoint.

What did Jack reuniting with Castiel mean to him?

It means everything to him. I don't want to say too much because I think it's all kind of there when we see it. It’s a huge moment for Jack.

Jack was very impressed that he could move the pencil. Working towards this idea that he can open up the dimensional rift and try to get Mary Winchester back, are we going to see him try and attempt that again, or has that not happened yet?

Going forward, you're definitely going to see Jack try to do that. He knows ultimately that the thing that's driving Sam and Dean is their mother. The way that Jack can be of service to them is to open that up and help Sam and Dean complete their journey in a way.

In the Western episode, Jack accidentally kills someone. How will that impact him going forward?

Jack at this point is really naive to the world and to kind of get his first taste of being responsible for something so terrible really weighs on him and throws him in a direction that he's not ready for. And, that's going to lead him to kind of make his next decision and his next progress of where Jack is. Moving forward, it’s him taking on that kind of darkness that he wasn't really ready for yet.

He overheard Dean and Sam talking and got hit by some truth bombs. Is that something that he still holds on to or has he gotten to know the brothers better, where he trusts them a little bit?

I mean, he's not their brother. I feel like he’s starting to feel like a Winchester because he - it's like you're kind of stuck with these people that are your family. Dean has these really harsh feelings towards him. But at the same time, Jack still really wants to impress them and be a part of that group. The truth bombs did happen, but he's still trying to carry forward and be part of the family.

At the end of Tombstone, Jack leaves. Can you talk about what we might see of him on his own? Is he working solo?

Working is a good way to put it. He's definitely trying to figure himself out and because of the guilt of what happens in "Tombstone," he really pushes himself forward.  He feels guilty and messed up for hurting this person who was innocent.
