Emily Deschanel: Very similar to David, except for the fact that we ended the season with the season finale -- David directed that episode. The kind of shoot-out scene took like three days to shoot. They're intense, but in a way nice to jump into strong emotions.

We shoot five scenes in a day on the show -- it's not like we take multiple days to shoot one clean. There's some really big conflicts that Booth and Brennan have in the first couple of episodes that you don't see very often. The writers are always taking things to the next level and doing different things.

It's hard because the character's named Temperance, but she's really based on Kathy Reichs.

It's just become this thing now that Emily and I really enjoy doing. I know we want to keep it a bit of a surprise for everyone. It's going to be a great opportunity to enjoy the 200th episode, but on top of it to kind of give something back to the fans. Emily's going to look so beautiful, as she always does, but classically beautiful.: They're going to have to deal with their different reactions to things, because of where Booth is -- in prison and coming out of there.

It's a lot of fun, and the two of us have a blast kind of stepping into whatever those characters are at times. Bones is going to have to re-evaluate the relationship in a way (e.g., Why is he acting this way?

The remains of a man who has been dead 16 years could be the point of origin in the entire government conspiracy that ultimately put Booth in jail.

Meanwhile, Booth is faced with a challenge from James Aubrey, a new and politically ambitious FBI agent.

It's always challenging when the storyline is of that nature. We've really been able to examine the character's relationships when they're at home and when they're dealing with the conspiracy -- how it ended last season. We've come back in a similar space for these charcters.

Things have changed dramatically, and I think this season we will see that the reward for all of it is going through this kind of fire they went through in their relationship and how it affects them and how it opens new doors. I can't say they were happy times shooting these episdoes.

Back in 2005, when a cocky FBI agent first joined forces with a bookish forensic anthropologist to solve crimes, David Boreanaz and Emily Deschanel never could have envisioned their mismatched characters sharing not only a home, but also a baby, in the year 2012. It's not fair for us to guess exactly what happened after that. But we're not having any bedroom scenes right now, thank God.

But here both actors are, sitting for their first interview in Booth and Brennan's cozy new living-room set — complete with crib and stuffed animals strewn about the floor. Boreanaz: Actually, for our first episode in the house, I thought it looked too perfect. TV Guide Magazine: Your exec producer Hart Hanson tells us he does want to show a sex scene next season, after the infant's older. I just had a baby [in real life], who comes with me to work every day. Boreanaz: They won't be attacking each other ferociously over steaks they're grilling outside. Boreanaz: We were going to take you there, but you're not allowed.

We continuously want to push the button of the competitiveness and the sexualityness. I'm very familiar with that kitchen counter over there. I'm sure there will be something as the series goes on.

TV Guide Magazine: Fans are keenly aware that some hotly anticipated moments in Booth and Brennan's relationship never played out on screen. Boreanaz: We have this way of showing but not showing.

There are definitely similarities between Tempe in the show and Tempe in her books. I'm about to turn 38 myself, so if we keep going, I may catch up to the books.
