Vixen has a flash back of her life with her old friend. She gets mad at her friend, for betraying her. They get into a huge fight. Vixen finally decides, she has no choice, but to hurt her best friend. When she claws too hard, she realizes, that friends can't always be there for you. Especially when you take their lives.
The song is Immortals, from a little bit of movies that I know you've seen before. I know I do animations with sad endings. It's just how I prefer to tell the story of Vixen. Also, Vixen is a totally different thing from Willowheart. Vixen is a wolf, Willowheart is a fox.
