When Alistair talks about drawing the line at orders to “put on a dress and dance the Remigold,” the localization notes in the toolset gloss “Remigold” as “Cancan”. Given the setting, though, I’m more inclined to picture it as the Fereldan equivalent to the Volta, a wildly popular (and bitterly denounced by moral authorities!) dance from 1500s Europe that was particularly favored in the court of Elizabeth I.
So feel free to imagine Cailan doing a controlled, rhythmic version of repeatedly kicking his half-brother’s fancy dress-wearing ass into the air. It certainly made my day.
