At the end of the second episode, Euron Grejoy launches a devastating attack on the Iron Fleet, which was stolen from him by his niece and nephew, Yara and Theon. During his siege, Euron lays waste to two of the Sand Snakes, Obara and Nymeria. Nymeria's weapon of choice is a bullwhip, and Euron strangles her to death with it before he hangs her from the front of the ship.
Perhaps the more poetic death of the two, though, is Obara's. Her weapon is a spear, which she uses to kill countless enemies, including Prince Trystane. Euron impales her with the spear, using her own weapon against her like he does with Nymeria. Additionally, the name of House Martell's throne is Sunspear, so spearing the late Prince Oberyn Martell's oldest daughter adds an extra layer of cruelty to her death.
