Regina Mills (mayor of storybrooke, wife of Emma swan, and mother of Henry Mills) had gotten into a huge argument with Emma ( wife of Regina mills, other mother of Henry Mills and sheriff of storybrooke). Emma left out of town for two weeks that turned into two years. Regina had been on the look for her but she failed the first few months but two years later something popped up that left clues for Regina but she knew she couldn't do this alone all she needed was Henry and Emma's parents to look.
