Will Amy Ryan's Holly Flax come back to The Office, and when? Producer Jennifer Celotta is talking about a possible return for Michael Scott's (Steve Carell) lost love.

Moreover, there's new word on when the Pam (Jenna Fischer) and Jim (John Krasinski) wedding may go down, how Dwight (Rainn Wilson) is coping with the loss of Angela (Angela Kinsey) and what Karen (Rashida Jones) will be up to when she returns.

"They're going to start planning their wedding, I can say that," Celotta says of Pam and Jim.

Co-executive producer Paul Lieberstein, who personally has some choice Office quotes as hated HR rep Toby Flenderson on the show, added, "We are following Pam and Jim outside [of the office]. I don't think we'll be back in the house, but outside of work."

So will they say "I do" before the current season ends?

"We’re not sure," says Celotta. "They’re definitely headed toward a wedding, that’s what we have in our minds, but we don’t know exactly when."

And it won't be all smooth sailing for PB&J.

According to Lieberstein, Jim's ex Karen, Rashida Jones, returns for the first half of a two-part episode in March for an episode called "Lecture Circuit" written by Mindy Kaling (Kelly), and it will reunite Karen and Jim's bride to be.

"Michael has been doing well at the office," Paul explains.

"And Wallace asks him to go around and talk to some other branches, and one stop is Utica. He has Pam with him as his assistant."

Will Karen confront the boyfriend-stealing, now-engaged Pam?

"Pam is very nervous and anxious to see Karen, and the storyline deals with that," Lieberstein says.

Meanwhile, it seems like Dwight Schrute is not handling the loss of Angela too well. For The Office's big Super Bowl episode, Dunder Mifflin is in need of a good old-fashioned fire drill, and per usual, Dwight Schrute will take things a bit too far.

"In an effort to do extreme disaster training, and frustrated with the way people are responding to him, Dwight sets fire to the office," Lieberstein says. "He locks everyone in the office and sets fire to it. Michael has to come and cool him down afterward."

So what about the fans' hope that Holly (Amy Ryan) will be back?

"There's a strong story for Michael coming up," Celotta teases, revealing that the producers are stalking pursuing Ryan to see if she might return before the season ends. "I don't want to say the storyline," Celotta says. "I like it to be a surprise."
