Joe, you were kind of talking about it just a little bit here in that last question but how do you try and maintain stability in the overall story you want to tell and the direction you want to take the show with the - so much change in the cast over the last couple of seasons?

Joseph Mallozzi: Well I mean, we go season by season really. You know, it's not like a, I guess, a bigger game plan in terms of several seasons down the line. We - at the end of every season, you know, we leave with usually our season cliffhanger and we kind of have more or less an idea of where we want to pick things up with the first episode.

We're really not that much beyond that. And then, you know, hopefully we get the, you know, the call from the network that tells us we're coming back for another season.

And after taking maybe a couple weeks off, we come back together and, you know, we spin out ideas and we say okay, this is what we'd like to do for the season.

Sometimes it's, you know, a very clear idea of what we want to do, you know, in terms of sort of a broad picture. In the case of season five, for instance, we wanted to open things up in the Pegasus Galaxy and that's the game plan we went into for the season and, you know, as well, you know, introduce Richard Woolsey as the new commander, and deal with Teyla's role as a mother and adventure. That's another thing we wanted to deal with along with some various other smaller stories.

Season four was a little different in that we came in and we knew we wanted to give the spotlight to each character and have them have their, you know, own separate storyline.

So we started on kind of a micro-scale and worked our way to the macro where we came in and we pitched up story ideas and those story ideas kind of dictated what the general theme of season four would be.

You know, the Wraith/Replicator war being a big one and sort of the weakening of the Wraith over the course of the season. And of course, one of the storylines that was dictated to us was the Teyla pregnancy that - you know, Rachel came in at the beginning of the season and we had planned to sort of go a little dark side with her character, and, you know, make her a little more colorful.

And, you know, when she announced her pregnancy we thought okay, well I mean, we could either continue with the storyline and shoot around the pregnancy -- which frankly, you know, always - never really works in television -- or we could just embrace it and make her character pregnant which is what we did.

And I think, you know, the storyline worked out very well. It dovetailed nicely with missing Ethosian storyline and ultimately Michael's designs on Teyla and the baby.

So, you know, we go from season to season. You know, I - hopefully, you know, the cast that we have now is a cast that we're going to keep for many seasons to come. But, you know, who knows?

And I put out a question to - a request to readers and the one question that came back they wanted to know was what is the future possibility of ever seeing Tori Higginson back as Dr. Weir again?

Joseph Mallozzi: To be honest, I think it's highly unlikely. I mean, you know, I kind of outlined sort of the situation where, you know, last season, you know, she came in and did a couple of guest spots for us and she was terrific, and she seemed very excited about the prospect of coming back.

And, you know, we pitched out the idea of the possibility of, you know, her coming back in and continuing the Replicator storyline which she was, you know, fairly - seemed very excited about.

And so, you know, Carl went off and, you know, he wrote the script and ultimately we contacted her about doing it. And, you know, initially she was a little reluctant and, you know, perhaps maybe thinking about her fans she was wondering if maybe there was a way to sort of create some sort of closure for her character.

And although I mean, we kind of wanted to keep the character alive, if basically she wanted closure then we would be willing to give her closure. And we told her, and then she was still reluctant so we ended up sending her a script to review, and ultimately she passed.

I mean, it's too bad. I mean, we would've loved to have her come back and, you know, and see her no the show but I - you know, I think at this point kind of she's moved beyond, you know, this show and is, you know, looking elsewhere. So, you know, we wish her the best of luck.

And like I said, she did a terrific job for us when she was here doing her three guest spots last season. And, you know, it's unfortunately we won't see her again in season five. But, you know, again, you know, it was her choice and we respect her decision.
