[Warning: Spoilers ahead for Sunday's episode of Game of Thrones“Sons of the Harpy."]

The death bells tolled once again on Game of Thrones.

Save for a miracle, Ser Barristan Selmy (Ian McElhinney) looks doomed after Sunday's violent episode. Selmy appeared to die after fighting off a dozen members of the Sons of the Harpy, the terrorist organization that has been wreaking havoc on Meereen. He fought alongside Daenerys' (Emilia Clarke) unsullied commander Grey Worm (Jacob Anderson), who also collapsed at the end of the episode, though his wounds did not necessarily appear mortal.

If Ser Barristan really is dead, that's a huge blow for Daenerys, who has already lost her other trusted advisor, Jorah (Iain Glen). Jorah is first up in the list of the episode's other big moves:

Jorah hopes to redeem himself. Tyrion (Peter Dinklage) angered Jorah by figuring out his whole story: Daenerys exiled him for spying for Varys (Conleth Hill), and he hopes to regain her favor by bringing her Tyrion. Jorah's plan has a tinge of irony because Tyrion was heading to Daenerys already.

Cersei has Loras arrested. Cersei (Lena Headey) armed The Faith Militant, giving the High Sparrow (Jonathan Pryce) military powers. First on their agenda: imprisoning Loras (Finn Jones) for being gay. It's all part of Cersei's war against Margaery (Natalie Dormer), whom she feels is usurping her power and influence over her son, King Tommen (Dean-Charles Chapman).

Littlefinger reveals (more) of his master plan. Littlefinger (Aidan Gillen) is among the most cunning people in the Seven Kingdoms, and he is truly playing the long game. After double crossing the Lannisters by arranging Sansa's (Sophie Turner) engagement to Ramsay Bolton (Iwan Rheon), his next move is to abandon the Boltons, whom he believes Stannis (Stephen Dillane) will crush if and when he marches on Winterfell. If that happens, Littlefinger believes Stannis will name Sansa Wardeness of The North — as she is the true heir to Winterfell and the people would respond well to a Stark occupying it. And if Stannis loses? She can marry Ramsay and exert power that way.

The Sand Snakes are loose. The late Oberyn's (Pedro Pascal) bastard daughters Obara (Keisha Castle-Hughes), Nymeria (Jessica Henwick), and Tyene (Rosabell Laurenti Sellers) finally made an appearance as they plotted to seek revenge for their father's death at the hands of The Mountain (Julius Bjornsson). They are as fiery and lethal as their father, and under the guidance of Oberyn's lover Ellaria Sand (Indira Varma) they are planning to harm Cersei and Jaime's (Nikolaj Coster-Waldau) daughter Myrcella (Nell Tiger Free), who is living in Dorne and is betroathed to Oberyn's nephew Trystane (Toby Sebastian). Jaime is attempting to rescue his daughter covertly in order to prevent a war, but the Sand Snakes want to start a war. We'll see which side gets their wish.
