These Are All of the Deaths in "House of the Dragon" Season 1

Ser Harrold Westerling (Graham McTavish) doesn't quite stick up for Rhaenyra when the greens announce their plans, but he doesn't go along with it either. He says that as Lord Commander of the Kingsguard, he doesn't have a role to play until there's a king to follow. Later in the episode, he tries to leave King's Landing, though whether he wants to go serve Rhaenyra or just go into hiding is unclear. He gets caught and is hung for this actions.
