The Evil Queen and Hyde continue on their quest to steal Dr. Jekyll’s serum; Snow looks forward to her first day back as a school teacher; and while Emma looks forward to Hook moving in with her, Hook finds himself trying to protect Belle from Mr. Gold, who has made sure she can’t leave the confines of the pirate ship. Meanwhile, back in the past, Rumplestiltskin helps Dr. Jekyll complete his serum to separate a man’s personality into two – good and evil – but his help comes with a hefty price.

The same model was used for the Darling House drawing room in the Season Two episode "Second Star to the Right": The wall panels by the windows, the windows themselves, even the curtains, all have the same design, but the checkered window panes in Alphonse's home were replaced with frosted window panes.
