"Mhysa" is the third season finale of the American medieval epic fantasy television series Game of Thrones, and its 30th episode overall. Written by executive producers David Benioff and D. B. Weiss, and directed by David Nutter, it originally aired on on HBO in the United States.
The episode revolves on the aftermath of the events instigated by " The Red Wedding": House Frey receives the Seat of Riverrun, Roose Bolton is appointed the new "Warden of the North", while House Greyjoy begins a new military campaign. In the North, Maester Aemon sends out ravens to alert the whole of Westeros about the arrival of the White Walkers. And across the narrow sea, the freed slaves of Yunkai hail Daenerys as their "mhysa", the Ghiscari language's word for "mother".
According to Nielsen Media Research, "Mhysa" was seen by 5.4 million household viewers in the United States, a twenty-eight percent increase compared to the second season finale, " Valar Morghulis". After its broadcast, the episode received generally positive reviews from television critics, with some of them addressing its anti-climactic closure of the series' third season, and its establishment of potential storylines for the fourth season, such as through the final scene's "glimmer of hope". The episode received a nomination for a Primetime Emmy Award for Outstanding Cinematography for a Single-Camera Series at the 65th Primetime Creative Arts Emmy Awards.
