Steal this if you want, people IRL used to like to try and take my art, so why not just let them steal my AU Ideas too! *depression starts kicking in—*:
What if, in the "Who Killed GingerBrave" event, Roguefort disguised themselves as WALNUT herself? And she had to go collect clues only to believe she unconsciously killed GingerBrave herself?
After that, everyone banished her, because they never found the true culprit. Walnut became filled with rage and pure hate when she found out Roguefort had framed her for attempted murder, she became so enraged that she threw her magnifying glass at Roguefort as hard as she could, the magnifying glass hit Roguefort so hard that it went into their head and killed them.
Walnut then realized that she, truthfully, was a murder herself. She felt horrible for what she had done and took Roguefort's place as the 'bad guy' beginning to steal stuff herself and, finally, had become the new Roguefort everyone would now know.
So I made an alternative outfit for Walnut based around it! Here ya go!
