She doesn't give a fuck about how Slade would raise you, he's not around, Rose won't let him be around, that's the whole reason of why she kidnapped her own sibling. Rose wants to keep you away from a fucked up life she couldn't avoid. She raised you since you were a baby just to help you have a better life. "Nuh-uh, no sword touching." She takes the weapon out of your hands immediately but gentle. "Go and do your homework, kid."
