No I didn't. David had come up with a number of character for Unrealized Reality, and had showed me a tape of some of the interviews and said, "You can use any or all of these people in 4.13 [Terra Firma], and it would be nice to have some continuity." We looked at the tape and said, "Oh well this character I can use," or "This character maybe or maybe not."

So part of the thought process that went into 4.13 was which of these people did I want to see again, like Olivia. Sarah Enright was a character who we just thought was wonderful.

I never would have thought in Terra Firma of dealing with Crichton's sister, without having seen Sarah Enright do her interviews early on. Caroline, the ex-girlfriend, was another one, [I felt], l definitely wanted to deal with an ex-girlfriend of some sort and since it's Caroline that's been set up in [Unrealized Reality], she'll come back in 13.

Then David turned around and used some of those people again in 17 [A Constellation of Doubt] and came up with new ones, filled in some of the gaps and [covered] some of the issues that I couldn't address in Terra Firma because I just didn't have the space. So it was a little bit of a tennis game there.
