The shocking final moments of "Game of Thrones" Season 6 episode 1, titled "The Red Woman," has given rise to a number of theories on how old Melisandre is and what it means in the larger scheme of things.

Fan theories note that if Melisandre is more than 100 years old, as revealed by Carice van Houten, chances are we'll soon find her connection with the Bloodraven, and that will potentially link Bran's story with that of the now seemingly dead Jon Snow. But if Melisandre is several centuries older, then she could be a survivor of the Doom of Valyria.

According to a Reddit thread, the final scene in "The Red Woman" could be an indication of Melisandre preparing herself to resurrect Jon Snow. As fans of George R. R. Martin's "A Song of Ice and Fire" and the television series know, Melisandre's necklace glows when she is doing magic, and it looks like her necklace did emit light before she took it off in "The Red Woman."

"I would say it appears she did some magic before climbing into bed," a Reddit user pointed out. "Whether it was taking a potion of unknown origin or otherwise having the Lord of Light act, there was something going on in that scene. My best thinking is that she sacrificed herself to save Jon Snow (only death can pay for life...). She wanted to look upon her true self one last time. She wanted to die comfortably in bed," the user noted.

Meanwhile, another user pointed out that Melisandre is suffering from a crisis of faith brought about by Stannis' defeat and Jon Snow's death, and her decision to remove the illusion of youth and rest in her true form "represents that exhaustion, and I think it will be the catalyst that allows her to bring him [Jon Snow] back."

The synopsis for next Sunday's episode of "Game of Thrones" has been released and it looks like we'll be seeing more of the Lannisters in this season's second episode. The synopsis reads:

Bran (Isaac Hempstead Wright) trains with the Three-Eyed Raven (Max von Sydow). In King's Landing, Jaime (Nikolaj Coster-Waldau) advises Tommen (Dean-Charles Chapman). Tyrion (Peter Dinklage) demands good news, but has to make his own. At Castle Black, the Night's Watch stands behind Thorne (Owen Teale). Ramsay Bolton (Iwan Rheon) proposes a plan, and Balon Greyjoy (Patrick Malahide) entertains other proposals.

"Game of Thrones" airs Sundays on HBO.
