'Game of Thrones' Season 6 spoilers news: Lady Stoneheart to emerge in season 6 finale? Is Sansa pregnant?

While she has yet to re-appear in the HBO series "Game of Thrones," Catelyn Stark is still alive (well, sort of) and kicking in George R.R. Martin's "A Song of Ice and Fire."

After her throat was slit at the Red Wedding and her body was unceremoniously dumped in the river, Catelyn (Michelle Fairley) was pulled out of the water by Nymeria, Arya's (Maisie Williams) direwolf and was subsequently brought back to life by Thoros of Myr (Paul Kaye) and Beric Dondarrion (Richard Dormer).

Since then, she has been traveling with the Brotherhood Without Banners, hunting down every last Lannister, Frey, and all other Westerosi involved in the killing of her family.

But while Lady Stoneheart, as she is known in the books, has yet to even be mentioned in "Game of Thrones," things may change in this Sunday's hotly anticipated season 6 finale.

While there has been no confirmation of such, the show seems to have been dropping hints all season long, with Catelyn being mentioned on at least three different occasions.

In episode 6, she appeared in one of Bran's (Isaac Hempstead-Wright) visions. In episode 8, she was the subject of a tense conversation between her brother, Edmure (Tobias Menzies), and her former prisoner, Jamie (Nikolaj Coster-Waldau). In the same episode, The Blackfish (Clive Russell) mentioned her while talking with Brienne (Gwendoline Christie) about Sansa (Sophie Turner).

While all of these may have nothing to do with an eventual Lady Stoneheart revelation, they could also have been intended to remind viewers about Catelyn.

And as Yahoo! reported, Turner may have slipped a major hint that the long-awaited character could soon pop up on "Game of Thrones." According to the outlet, while playing a game of Two Truths and a Lie, the actress dropped the following statements:

"Ramsay dies."

"Lady Stoneheart returns."

"Arya checks three people off her list."

As fans know, the first has already come to pass. The second and third have not. But given that Arya would have to kill Cersei (Lena Headey), The Mountain (Hafthór Júlíus Björnsson), and Ilyn Payne (Wilko Johnson) all in one episode for the third statement to be true, it could only be assumed that Turner's second statement is the other "truth."

Meanwhile, there has also been a lot of speculation surrounding what Ramsay (Iwan Rheon) said to Sansa before he was eaten alive by his hounds in the previous episode.

Fans have been trying to figure out what exactly the villain meant when he said, "You can't kill me; I'm part of you now."

Did he mean that he has left Sansa with such huge emotional scars that she is forever altered? Or was he somehow aware that she was carrying his child?

In an interview with Refinery29, Rheon tried to explain the statement, saying, "By doing all these horrible things to her, he has left his mark on her and therefore he is part of her."

When asked about the possibility that he knew she was pregnant, Rheon answered, "Well unless Ramsay has got an incredible talent of being able to spot pregnant women, then I don't know."

"I don't know if he has examined her or anything," he said. "I have absolutely no idea, so you'll have to just wait until next season to find out."

The "Game of Thrones" season 6 finale airs Sunday, June 26, at 9 p.m. ET on HBO.
