Coming up in primetime television. has a big CW return for the week of December 15 as well as saying goodbye to a talk show legend, holiday episodes and classics, baby news, a TNT renewal, a FOX interview, show teasers, casting and more in our latest Primetime Dish column…

Bob’s Burgers:
In FOX’s Sunday December 14 9:30 PM episode titled “Tina Tailor Soldier Spy,” Tina attempts to find the mole who’s giving away cookie secrets by going undercover in her old Thundergirls troop, and Linda goes blonde.

Emily Deschanel, who stars as Bones in the FOX series, and David Hornsby (“It’s Always Sunny in Philadelphia”) are expecting baby number two! Her first pregnancy was written into the series and TVLine has learned that the show plans to do the same for her second one.

Interview! sat in on a conference call with Producer Stephen Nathan. When asked how he came up with the details for the FOX series’ 200th episode Nathan shared, “Well, I think coming up conceptionally with this, we wanted to go back to something that was classic because after ten years, we’re moving into the classic category; not many shows last for 200 episodes. I think there have only been 24 dramas in the history of television from what I’ve been told. We wanted to do a classic examination of the show and of the romantic nature of the show. This style, this time, really sets it apart and allows us to highlight that aspect of our series in a way no other time really could. We also got a chance to reintroduce Booth and Brennan, see the initial attraction and the blossoming of their romance, again, in new circumstances.” Tune in for the milestone episode titled “The 200th in the 10th” on Thursday December 11 at 8:00 PM.

Kirsten Dunst (“Spider-Man” films) and Jesse Plemons (“Breaking Bad”) have landed leading roles on the FX series.
