Warning: The following contains possible spoilers for season six of HBO's "Game of Thrones."

Jon Snow may get all the headlines, but he wasn't the only character in season five of HBO's "Game of Thrones" to receive an ambiguous death. Myrcella Baratheon also drew what appeared to be her last breath, though fans weren't wholly convinced.

During the season five finale, "Mother's Mercy," Jaime and Myrcella leave Dorne on their way back to Westeros and share a truly touching moment with one another. Myrcella reveals that she is aware of her true parentage and that it doesn't bother her. She says she is glad that Jaime is her father. Despite the unsettling circumstances around her birth, it is one of the sweeter moments in a show that is, for the most part, dour and grim.

Unfortunately, it is also a fleeting moment. Soon after their heart-to-heart, Myrcella falls to the ground, poisoned by Ellaria. We are led to believe that she dies in Jaime's arms, though since this is "Game of Thrones," we aren't 100 percent sure.

In George R.R. Martin's novel series "A Song of Ice and Fire," Myrcella is still very much alive (though injured). Given that the show has caught up to the narrative timeline of the books and even surpassed it in some instances, there's no way to tell which cliffhangers are real and which will be resolved eventually. Unfortunately for the TV-version of Myrcella, it does seem as if she is truly dead.

"Game of Thrones: The Noble Houses of Westeros," a new book from HBO which details the complex histories of the major houses, Myrcella has gone to the great castle in the sky. The text explains that she "died in the arms of Jaime Lannister, who she acknowledged as her father before her death."

Cersei will be none too pleased to learn of yet another one of her children's death.

"Game of Thrones" is expected to return in late April or early May of 2016.
