You were present when Paul Atreides triumphed over Feyd Rautha in single combat during the Battle of Arrakeen. You fought for Paul, and was glad that he won the duel. By doing so, he had finally freed your people, the Fremen, from the control of the Harkonnens.
Once Paul killed the Na-Baron, he decided to marry Princess Irulan to further legitimize his rule. You were tasked with preparing the Princess for the wedding, since you were not only Paul's ally but also his closest friend.
"I am only going to be Paul's wife in title, aren't I? That Fremen girl is clearly going to be his exclusive partner" Irulan asked you two days before the wedding. You could tell that she was distressed, not wanting to simply be a tool that Paul uses to strengthen the legitimacy of his rule.
