After Natalie Dormer's character in HBO's "Game of Thrones" was killed off in the season 6 finale, fans of "Elementary" are hopeful to see the actress reprise her role as Sherlock's slyest nemesis.

Dormer appeared in the first three seasons of CBS' crime drama inspired by the iconic book series written by Sir Arthur Conan Doyle. She portrayed the role of Sherlock's (Jonny Lee Miller) lover Irene Adler, who later turned out to be the criminal mastermind named Jamie Moriarty. She was last seen in season 3, after she wrote a letter for Sherlock in prison, warning him of the ongoing game between them.

Since the character was not killed off in the series, it means that there is still a possibility that she can return to the show. And after Dormer's character Margaery Tyrell has been confirmed dead in "Game of Thrones," the actress will have more time to work on the crime procedural drama.

While the network has yet to confirm if Dormer will be part of season 5, there are speculations that Sherlock and his partner Joan Watson (Lucy Liu) will look back at their relationships with their families next season.

In season 4, Sherlock's dad Morland (John Noble) followed him to New York to ask him to forget about their tumultuous past. But the former Scotland Yard consultant later on found out that Morland took over the leadership of Moriarty's crime organization, which made him hate his father more. However, it was also revealed that the reason why Morland joined the organization was to dismantle it from within to assure the safety of his son.

Meanwhile, Watson is expected to meet her biological father in season 5 after she met her half-sister Lin (Samantha Quan) in the previous season. Fans are also looking forward to seeing the development in the relationship of the half-siblings when the series returns this fall.

"Elementary" season 5 is slated to return to CBS on Oct. 2.
