Linda Hamilton, Lauren Cohan Linda Hamilton, Lauren Cohan

Bride or groom's side? If you're attending the big Chuck wedding, perhaps the safest answer is "neither."

Any spy knows that their loved ones could be used against them, and on Monday's episode "Chuck vs. the Last Details" (8/7c, NBC), Chuck (Zachary Levi) learns that new nemesis Vivian Volkoff (Lauren Cohan) has captured his mother, Mary Bartowski (Linda Hamilton) while she was on a mission.

"We're five days away from the wedding, and Chuck and Sarah (Yvonne Strahovski) thought they had the week off," co-creator Chris Fedak tells "They thought that, you know, they could stay in the apartment, lay on the bed and drink mimosas. Instead, they have to go out on one more mission to save Mom Bartowski."

No mission on Chuck, however, would be complete without some personal Bartowski angst. "It's also a test for Chuck because rarely has he had to deal with a disagreement between his mom and his fiancée," Fedak says. "In this episode, that is a central part of it. Not only is it Chuck trying to save his mom, but also trying to navigate the waters of the mother-in-law/fiancée relationship. Not fun for them, but funny for us."

The engaged couple won't be the only ones dealing with stubborn Mom Bartowski, though. Vivian will also have her hands full with her. "Mary is a terrible hostage," Fedak explains. "She's an absolute, awful hostage."

Vivian has come a long way from the privileged but sheltered Oxford grad who only recently discovered that her dad, Alexei Volkoff (Timothy Dalton), was not a mild-mannered oil executive but a notorious international arms dealer. In some ways, Fedak acknowledges that Vivian's turn to the dark side mirrors the moral journey of Star Wars hero Luke Skywalker.

"I don't think that's too big of a stretch at all," Fedak says. "I think Vivian Volkoff has definitely been experiencing a darker story than say, Chuck Bartowski, who's kind of found himself falling into the good guy world, protected by Sarah and Casey (Adam Baldwin). Whereas with Vivian Volkoff, she's fallen into a world of bad guys. She's been manipulated by them and trained by them and taught by them. Instead of seeking protection from Chuck and his gang, she winds up with Riley (Ray Wise)."

It remains to be seen how far the Skywalker parallel goes. As we discovered in the last episode, her father is the mysterious Agent X, someone she vowed to destroy.

Who do you think Vivian is trying to kill at Chuck's rehearsal dinner? Could she turn on her father when she learns his true identity?
