Vulpes wants to learn how to dance the cha-cha in order to further blend in when he's spying on Vegas. F!Courier (who is under the employ of Mr. House) is an authority on all things Pre-War and swingin', but is rubbing shoulders with the Legion to get intel for her boss. Vulpes requests that she give him dance lessons.

Bonus if Caesar has them dance in his tent, while he gives "Dancing with the Stars" criticism ("Pick those feet up, Vulpes, this isn't a fucking waltz!").
