Although Jess and Nick have finally gotten together on hit comedy "New Girl," don't expect them to immediately live happily ever after. 

Jess (Zooey Deschanel) and Nick (Jake Johnson) embarked on a romantic relationship at the end of season two. However, their relationship doesn't signal an end to their personal issues. 

Liz Meriwether told TVGuide that issues will still persist, such as Nick's unstable career. "They're still dealing with all those issues," Meriwether said. "Schmidt is actively trying to break them up, so they're battling Schmidt too. They have a lot going against them and we'll see if they can make it."

The upcoming season of "New Girl" will also feature appearances by some of the characters' family members. Jess' (Zooey Deschanel) sister will be debuting on the show in early 2014. Co-producer Brett Baer told TVLine said that her sister will "add a depth charge in the fabric of the loft." 

There is a chance, albeit a small one, that Zooey's real-life sister, Emily, could appear as Jess' troublemaking sister on the show. "It's an idea that is obviously right in front of us and it's definitely something to explore," said co-producer Dave Finkel. "But [Emily] has her own television show, so we're not sure if it's even a possibility." 

Viewers will also be getting acquainted with Schmidt's (Max Greenfield) family in season three. 

Schmidt will have a bit of trouble with his love life next season, which will prompt some soul-searching. "He's going to slide a little bit and not be so on top of his game," Finkel revealed.

Baer added, "He's definitely on a journey to figure himself out this season. He's going to be forced to confront himself, and get in touch with the little guy inside of him." While on his personal journey, viewers will meet some of his family members, who will appear in the second half of the season. "You'll get a vision of what his childhood and homelife were like growing up, the way we did with Nick last year," Baer confirmed. 

The new season will also see the "New Girl" living up to her namesake. As the new girl at her teaching job, Jess will have a hard time fitting in with the "cool" teacher crowd, and will be given a hard time by two "mean girl" types who dislike Jess' goody-twoshoes personality. 

Damon Wayans Jr. will also reemerge next season to reprise his role as Coach, a character he played in the show's pilot. At the time, Wayans could not appear on the rest of the season because of his commitment to "Happy Endings," which was recently canceled. 

TVLine reports that Brenda Song will also make a brief comeback in the third season. 

Season three of "New Girl" premieres on Fox on Tuesday, Sept. 17.
