Andrew Rannells, Lena Dunham

Hannah's (Lena Dunham) gay ex-boyfriend and ex-roommate, Elijah (Andrew Rannells), ousted himself from the group at the end of Season 2, and now he's back, making his return to Girls on Sunday, Feb. 16 (10/9c, HBO). But he's not back in Brooklyn yet.

"We shot in the North Fork of Long Island," Rannells told TV Guide Magazine at the show's red carpet premiere earlier this year. "Everybody goes to this beach weekend. Things sure do get weird." 

Despite the weirdness — think synchronized dance parties and skinny-dipping — Elijah makes an effort to achieve normalcy with the quirky female foursome after he was shunned for sleeping with Marnie (Allison Williams) last season. "He's on pretty good behavior for the most part," says Rannells, who was upped to a series regular for Season 4 and will also appear in the remainder of Season 3. "Elijah is trying very hard to get back into the circle of friends because he did not leave on the best of terms with everyone."

He is, however, on great terms with somebody else — a new boyfriend. Danny Strong (Mad Men) who happens to be the real-life beau of Zosia Mamet (Shoshanna), joins the cast in a recurring role. "Danny is fantastic. [He's] very, very funny and a fantastic writer, " raves Rannells of his on-screen love interest, joking, "He's a very good boyfriend!"

Strong isn't the only guest star to stop through New York. The Blacklist's Amir Arison, who was introduced in last week's episode as Hannah's head-butting co-worker at GQ, will return for two more episodes later this season. "Deep down inside of messy Hannah is an incredible light and wit and talent and sharpness so that all comes through," Arison admits of Dunham's character, who overshadowed him in last week's hostile office meeting scene. As for Dunham, herself, there's no bad blood between the two on set. "It is not a mistake she is where she is. She's got the speed brain of Robin Williams, the directorial awareness of Woody Allen and the heart of an adorable 25 year girl," says Arison. "All mixed together, she's a focused leader and the best scene partner. She's an absolute dream."

With all of the girl fighting that goes down in North Fork, we're not so sure Marnie, Shoshanna or Jessa (Jemima Kirke) would agree.
