'Once Upon a Time' Episode 18 Photos: The Root of the Queen's Evil in 'The Stable Boy'

While Emma keeps looking for the proof that will clear Mary Margaret in the murder of David's wife, Kathryn, the fairytale world takes us all the way back to Regina's early, pre-Evil Queen days. She must choose between betraying her mother (guest star Barbara Hershey) by marrying for love or choosing royalty and living a loveless life. We also find out why the Queen hates Snow White so very much. "The Stable Boy" airs on Sunday, April 1 at 8pm on ABC.
