New Girl fans will soon see Jess (Zooey Deschanel) go to prom, and she might be doing it with style. Or should we say, with Stiles. Dylan O’Brien, who stars as Stiles on MTV’s Teen Wolf, will guest-star in an upcoming episode of the Fox comedy, the network has confirmed. (TVGuide.com first reported the news.) In the installment, flashbacks will reveal how our main characters lost their virginity, and in Jess’ storyline, she attends prom with a sensitive, guitar-playing dreamboat (O’Brien) who aims to make her first time something to remember. In other flashbacks in the episode, which airs April 30, Dennis Farina is slated to return as Nick’s dad, and Merritt Wever (Nurse Jackie) plays Schmidt’s girlfriend.
