In the final four episodes of Medium, the show has been filled with both the supernatural and marital conflict as Kelly Preston guest stars as a venture capitalist who decides to independently fund Joe Dubois (Jake Weber) and become a business partner while Allison (Patricia Arquette) helps a family ease their concerns that their new house is haunted in the season finale "Drowned World," airing Monday, May 12 at 10pm on NBC. With Medium about to wind down for the season, The Deadbolt caught up with Kelly Preston and show regular Jake Weber on a recent conference call with a select few outlets to talk about his solar powered business endeavor, their belief in the supernatural, whether there's an open door for Kelly's character to return, and more supernatural goodness as the season comes to a close.

THE DEADBOLT: Jake, I was wondering what exactly is the function of your solar power-based invention?

JAKE WEBER: I have no idea.

THE DEADBOLT: You don’t know what it is?

WEBER: It’s something that Glenn [Gordon Caron] came up with at four in the morning. It’s some sort of a solar generating system that can take solar power and magnify it or make it more efficient, make it more - I guess, kilowatts or watt or kills...

KELLY PRESTON: You know, those.

WEBER: You know, those units of power that we all enjoy and live with. Somehow it makes it more efficient, I’m not sure. I don’t think there ’s an exact science in this. I think this is more of a sort of TV invention than anything that actually has utility.

THE DEADBOLT: For both of you, what are your personal views on the phenomenon in Medium or the paranormal in general?

WEBER: Well, I have more of a Philistine view on this than Kelly. What I don’t know would fill a book. That’s all I really can say because I really know very little about this and I have - I know that people have had sort of paranormal and psychic experiences. I have not. But I’m open to offers.

PRESTON: And for me, I just know that, you know, spiritually I’m not my body, that I am a spiritual being and I’ve lived before, and will live again. So any sort of thing in that realm, I know that there are a lot of people who are able to perceive other things. And I think it’s very cool.

THE DEADBOLT: Kelly, your character’s story arc spans four episodes. Did they leave a door open for you to return?

PRESTON: They did leave the door open a crack, I guess. I mean, she does do something that’s pretty - seemingly final. But, there are always so many possibilities in Medium, even if in the future that it was discovered that [I died] - because I don’t die, just so you know. But in Medium, that’s never a closed door.

THE DEADBOLT: Good point. On a show like this, if you did die, you could come back.

PRESTON: Exactly. It gives you another whole arc.
