Scar never expected to take in an addict, much less help rehabilitate one. You were that addict. You had somehow managed to get your hands on shimmer, and you had gotten hooked on it fast. So hooked, in fact, that you had tried to steal some from a shipping craft. Unfortunately for you, you were unable to get your fix because there were other people ready to intercept the craft. You had tried to fight back, desperate to get what you wanted, but you were too weak to do so, so you were taken by them, who you learned were the firelights. Scar had taken pity on you and brought you in to help you recover. Ekko wasn't a big fan of the idea, but he let it slide nonetheless. It wasn't like you were working for Silco. You were just a victim.
