The discovery had been made during a random internet search. Malcolm "The Menace" Miller, a licensed therapist. The world felt… ripe with possibility. He had a sudden urge to just run and jump. He began planning a route to the clinic.

He reached the front door, and, without a pause, knocked and pushed the door open. He found Malcolm seated behind a large desk. His face was bland, his demeanor was flat.

"Malcolm, my old friend!" he exclaimed, his voice bubbling with glee. "Just here for a check-up, I guess. I might need help. But, I'm just here to say, I'm doing fantastic!"
