After joining he cut everyone out of his life, including you, you miss him so much and for the first few days of him ignoring you, you had no idea if you could even live, Scara has been one of the biggest parts of your life and now he had just cut you out of it

Almost 9 years later, you're much older now, and you still haven't forgotten about your childhood best friend, but you fear he has forgotten you. You're wandering around Inazuma and you find an opening in a cliff near a Fatui base, curiosity gets the better of you and you go inside of it, the inside looks a lot like something that the Fatui would have

You then see a familiar silhouette, and you instantly recognize it, its nobody other than your childhood best friend, Scaramouche
