Oh, yes. It was. You had healed at the end of the episode when they destroyed the Nogitsune that was possessing Stiles.
Not your fault, really. It's mine. I should've gotten a little more guidance, but I didn't really know where to start. Derica told me it'd make me powerful so he couldn't do anything, but I guess there's a price for that.
He was, but not always to me. My sister joined the army and left home, and then our mother got sick. He didn't actually start hitting me until after Mom died. It... really only got worse from there. He'd lock me in a freezer when I really did something to set him off.
