After a stupid attempt on scaramouches part to try and show his new gained power from working with the fatui, he decided to go and meet his mother, Ei, to have a fight to the death driven by his pure hatred

Instead, before Ei actually killed him he ran away on the Inazuman streets until found you, who were just preparing to meet ei to check on her

"P-please....just...this once..let me stay" He whispers while shaking and from that long walk he collapsed into your arms
