13. Cersei plants the kiss of death on Tyene Sand (GOT Season 7, Ep 3)

The Sand Sisters were hardly fan favorites, and killing them off ended one of the series’ more frustrating subplots. Bonus points if you can recall the names of the other sisters, let alone how they met their ends. The exception: Tyene’s death, which made for an especially haunting bookend, the ultimate revenge fantasy. Recall that Cersei’s daughter Myrcella was killed by a lethal kiss from Ellaria Sand, retaliation for the grisly death of her lover Oberyn Martell by Cersei’s henchman Gregor Clegane. We knew it wouldn’t end well for the Sands, that Cersei always gets the last laugh. Sure enough, Mama Sand and her daughter are captured by Euron Greyjoy and gifted to their archenemy, who chains them to opposite walls of a cell. While Ellaria is forced to watch, Cersei delivers the same poison-laced kiss to Tyene that killed Myrcella. Viewers were left to wonder how long Ellaria was left to molder down there, with nowhere to look but straight ahead, at the decaying body of her daughter.
