Sir Callister and Mr. Rinnes

Jekyll and Hyde Musical AU were Dr. Jekyll doesn’t experiment on himself, rather the disgruntled and ignored younger son of the wealthy Callisters who strives to be like his older brother for his parent’s approval. Due to some tampering of the chemicals by Miss Carew’s last love, the experiment goes awry and a calmer, reserved, and aloof personality emerges from the fun loving goofball Aaron.
