I heard that the Equestria Girls series could come to an end along with FIM but it doesn't have a proper ending in my opinion. So I thought I'd share my idea for a series finale.
A graduation special with the rainbooms discussing their future goals once they finally leave high school. However, Sunset Shimmer doesn't have any plans at all. Since she's no longer celestia's student and her chances of being a princess is long gone, she has no idea what her purpose in life is now and what's worse, her friends will be gone and she will be all alone once again.
That's my idea for a plot. Do you have one? Leave a comment.
