Imagine: Peter when he meets you, Lydia's sister.
"You."You narrowed your eyes at the older man in front of you.
"Me."He spoke, looking down.
Derek had told him earlier that you'd be coming over for a pack meeting and explained that you were Lydia's older sister. You had been pretty pissed that Peter activated Lydia's inner banshee because it hadn't been easy for you when an omega attacked you and activated yours. You had never wanted Lydia to go through that.
"You are the werewolf that attacked my baby sister?"You questioned.
"Yeah, about that I was in a pretty bad place, you-"Peter started to explain.
You cut him off by punching him square in the face.
"Wow!"You exclaimed."I've never punched a werewolf but that felt good!"
