"Game of Thrones" star Maisie Williams will reportedly make her third appearance on "Doctor Who," sometime this season.

According to the Mirror, series writer Sarah Dollard appeared over the weekend with Executive Producer Steven Moffat at MCM London Comic Con, where she confirmed that Williams' immortal Ashlidr will return in the 10th episode.

That's reportedly the same episode that will see the departure of Jenna Coleman as Clara Oswald. (Before you get too excited, no, Williams isn't destined to become the Doctor's new companion.)

Williams made her "Doctor Who" Oct. 17 in the fifth episode "The Girl Who Died," where she played Ashlidr, a Viking who's effectively made immortal by the Doctor after she sacrifices herself to save her village from an alien invasion. She returned in the following episode, "The Woman Who Lived," as a highwayman in 17th-century England.

"Doctor Who" airs Saturdays at 9 p.m. ET/PT on BBC America.
