Complete story — includes the ending
In the past in Victorian England, Jekyll petitions the Academy of Science for membership but Dr. Lydgate rejects him. Rumplestiltskin arrives and magically perfects Jekyll's serum; Jekyll transforms into Hyde, who blackmails Lydgate for Jekyll's membership. Mary is Lydgate's daughter and Jekyll's unrequited love; she and Hyde fall in love. Jekyll accidentally fatally defenestrates Mary; he frames Hyde. In Storybrooke, Gold imprisons Belle on the ship to protect her from Hyde; but it is Jekyll who tries to kill Belle in revenge for Rumplestiltskin's role in Mary's death. Hook saves Belle by killing Jekyll, and Hyde dies of identical wounds; Regina asks Emma to kill her if necessary to stop the Evil Queen. Gold warns Belle that their child will need his protection. Mary Margaret resumes teaching, and her assistant Shirin inspires her to draw on her life as Snow. Shirin is secretly Princess Jasmine, working with the Oracle to search for Aladdin.
