8. Daenerys locks Xaro Daxos and Doreah in a vault (GOT Season 2, Ep 10)

There are quite a few executions in GOT that tease viewers with only a hint of what’s to come rather than depicting what actually does. It’s a sinister gambit, inviting audiences to conjure horrific outcomes of their own. (Remember Season 3’s Sorcerer in the crate?) When Daenerys returns to Qarth after successfully retrieving her stolen dragons, she confronts Xaro Xhoan Daxos, the wealthy merchant who betrayed her in his bid to become the King of Qarth. Discovering that Daxos’s wealth is a facade and his vault is empty, Daenerys exacts her revenge by sealing him and her handmaiden Doreah, who also betrayed her, inside the vault. It’s a ruthless move that (presumably) subjects the pair to a slow, agonizing death, entombed in darkness. The takeaway: cross the Queen of the Andals at your own peril.
