Well it's basically what the title says. But I kept it short. I was mainly focusing on Virgil first joining The Darkside and leaving. Keep in mind that with the upcoming Sander Sides videos this may not be accurate at all. But I might as well have some fun with my little theory :P I will be writing the other darksides into this, but since I don't know their names or what they represent, I'll just put darkside 1 or 2 or 3. Once they're revealed, I'll add their names. Enjoy! (Artwork does not belong to me)
