You and your three brothers are all werewolves. Jack is the oldest, Noah is the second oldest and Alex is the next youngest.

Jack and Noah both have control of their wolf forms but you and Alex do not.

You are sneaking back into your house through the window of your room with torn up clothes and foreign wolf fur on you, and Jack can smell it.

Jack - "Look who's finally back. Where the hell where you? And you have the scent of another wolf on you."

Noah - "Why are your clothes torn up?"
