Twilight, in her first fight, utterly destroys her opponents. For about five minutes. Then things take a turn for the worse; Spike gets burned and sent to the hospital, and Twilight goes into a rage for weeks on end. Years later when Twilight remembers the incident, a image burned into her mind melds with a more recent one: eyes flashing from normal to green and slitted, and she stumbles onto something that shakes her foundation.
