Brighttu in Dune

What happens when you put Brighttu in Dune.

Being the Great granddaughter a million times over of the great Paul Atreides comes with a lot of pressures and since all the houses are at peace and chill with each other what's the harm in some good old harmless sleeping with your worst enemy who also happens to be your brother's best friend to relieve some of that fresh. It's not like your'e going to have to get married to him or anything anyways.
