The Evil Queen is continuing her quest to wreak havoc on the heroes in season 6, episode 4, of Once Upon a Time, titled “Strange Case.”

According to the official episode description from ABC, “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.”
