Brenna, oldest & core of the 3, has been in love with Fin since they were kids. When Cabhan's mark showed up when they were teens, showing him a descendant of the enemy, she buried her feelings, tolerating his presence as a friend. When it became clear that Fin needed to be part of their circle, Brenna was forced to put her hurt & anger aside. As they worked close to defeat Cabhan, the old love bubbled to the surface too strong to set aside again.
