Allison, what's your favorite artifact that you've got to play with on "Warehouse 13"? And Neil, is there a prop or anything that you particularly enjoy working with?

ALLISON SCAGLIOTTI: I say this every time, but it really does hold true. My favorite artifact is Edgar Allan Poe's pen. And if you're not familiar with Edgar Allan Poe's pen, it makes whatever you write actually happen. So I tend to joke, but if I had it, I wouldn't joke. I would write my own multimillion dollar movie contract and draw a picture of the perfect boyfriend and the deed to a cottage on Oahu. So that's why I like that.

Not that you've given this any thought.

(Laughter.)

ALLISON SCAGLIOTTI: No. Top of my head.

Don't think so small.

NEIL GRAYSTON: Mine for "Eureka" -- I've never actually got to play with it myself, but there's this thing called -- I think it's called the Sky Cruiser or the Sky Bike. It basically just looks like a jet ski. The idea of it is that it's a flying bike thingy. Just the, like, inner 10-year-old, the idea of being able to jump on a thing and fly around everywhere is the most exciting thing to me ever. So yeah, I totally want the Sky Bike or at least a scene where I'm on it flying through the air in the sky. Then I can be, like "Yeah, all right. I flew. It was awesome."

The concept of Fargo on a Sky Bike is terrifying.

NEIL GRAYSTON: It is very, very terrifying.

ALLISON SCAGLIOTTI: So scary. NEIL GRAYSTON: It would probably be more of a (pretending to take off and then crash).

ALLISON SCAGLIOTTI: Liability for the network.

NEIL GRAYSTON: Yeah.

ALLISON SCAGLIOTTI: Major.

Can you talk about Felicia Day coming on "Eureka"?

NEIL GRAYSTON: Yeah. It's been -- that's been really fun, actually. Felicia Day and Wil Wheaton and Fargo have a sort of thing happening. Just put it that way. And it's really given me a chance to have a bigger story and everything like that. But, I'm just going to go with the two of them. They both fit in so well with this show. Their sense of humor, the way they are just as people that it's -- yeah, it's just been really great having them just on set. They're funny. They're clever. And they really bring everything to it. I mean, I guess you've seen the dailies and stuff, and it's -- yeah, it's added this other little dimension of just super fun. It's also cool. Felicia writes, produces, and whatever with the guild and everything. So just to be around people like that who are – you know, she's on the show, but she's also making her own show as we're doing it. She's writing it and everything. It's kind of inspiring too just to have, hardworking people who are doing all this other stuff. it's been a really nice, fun thing. They're a really great addition. Kind of really excited to see how everything turns out. They started out -- Wil was going to just be on one episode, and now he's doing -- I think he's in half the season. Felicia's also in a lot of episodes during the season. So they're not like guest stars. They're kind of like, yeah, new members of the cast. So it's been great.

ALLISON SCAGLIOTTI: Also known as the reigning prince and princess of the geek world.

NEIL GRAYSTON: Yeah. I'm kind of in awe every day. They've got all their gadgets and their tech and everything, and then I'm pulling out my iPhone 3GS, and they've got all their fancy iPads and everything. I'm like, "Oh, I'm just going to hide this."

Is there a new love interest for Claudia? Was that what we were seeing there in the preview?

ALLISON SCAGLIOTTI: No, that's Claudia's brother. Joshua Donovan comes home for the holidays, which is another way for Claudia's just immeasurable excitement for the Christmas season.

NEIL GRAYSTON: See, you're not the only one. His hair was different. That was the thing. Because I was like, "Who's that guy? He looks familiar." And she's like, "That's my brother on the show."

ALLISON SCAGLIOTTI: That's my brother.

NEIL GRAYSTON: I was like, "Oh."

ALLISON SCAGLIOTTI: He's a super hipster. That's why.

NEIL GRAYSTON: Okay.
