“Elementary” executive producer Rob Doherty and co-producer Jeffrey Paul King live-tweeted the show’s Season 5 premiere last night, and during their exchange of tweets with fans, the duo teased which fan-favorite characters might be returning for the new installment.

When a fan asked if they have any plans to bring Moriarty (Natalie Dormer), Kitty (Ophelia Lovibond) or Ms Hudson (Candis Cayne) back into the CBS series this season, Doherty and King revealed that viewers might see one of the mentioned characters after the holidays.

Moriarty has not appeared on the series since the twelfth episode of Season 2 due to Dormer’s busy work schedule. Although Dormer’s “Game of Thrones” character has already been killed off in Season 6 of the HBO fantasy drama earlier this year, Doherty told Entertainment Weekly that it doesn’t            guarantee that the actress will be returning to “Elementary” in the current installment.

“I can say that there is always a chance of seeing the return of Moriarty,” Doherty said. “[But] at the same time, ‘Game of Thrones’ was never the only obstacle between us and Natalie. She’s extraordinarily busy, tends to have multiple projects going on at one time, so we’ll talk as we always do and look for a window.”

Kitty, on the other hand, has not been seen on the show since she jetted back to London at the end of Season 3, episode 12. During her 12-episode story arc, Kitty had become one of the most developed characters on the show, and given the viewers’ sadness over her departure, fans clearly want to see more of her.

Meanwhile, transgender Ms. Hudson last appeared in Season 3, episode 7, and because of the show’s pretty unique incarnation of the character, it won’t be a surprise if she’s the one who’s coming back to the show.

While it’s unclear who among Moriarty, Kitty and Ms. Hudson are returning, Doherty and King revealed in a tweet that there’s a great possibility that Joan’s (Lucy Liu) stepsister, Lin (Samantha Quan), will show up this season.

Unfortunately for Rhys Ifans’ fans, Doherty and King tweeted that the Welsh actor might not be reprising his role as Sherlock’s (Jonny Lee Miller) brother, Mycroft, in the new season due to another project he just booked.
