Amnesia

You hoist yourself up so you're swinging in mid-air. It reminds you of a scene form The Matrix. You swing foreward and jump. Your feet smack into his face. He falls backwards. You fall with him. You land sitting on his chest at the bottom of the stairs. He struggles trying to get away. You start attacking him with your fists. BANG! BANG! BANG! Charlie screams louder and louder. Then with one final SCKRUNCHGGS! his screams stop.
You check his pulse.
Still strong.
You stand up, and leave his body lying there, as you exit the big double doors.
