Headcanon: Musa and Brandon as close friends.
Musa and Brandon became closer around after Lord Darkart was defeated and She and Riven started going steady. It was actually Brandon who helped bring the to closer together in the first place. Brandon acted as an “interpreter” for Riven. Often times when Musa became upset with Riven, Brandon would step in and try to advocate for Riven’s feelings. He also was the one who explained to Riven why women are so “weird.”
Throughout the relationship Musa and Brandon talked more and more and realized they had a shit tone in common. Musa really admired Brandon’s taste in music, while Brandon loved all the new music Musa introduced to him. They also bonded over losing a parent, Musa with her mother and Brandon with his father.
They also laughed at each other for hours and hours discussing what it was like living with royalty.
