Have you ever seen two people meet and know immediately that they just couldn’t stand each other? That’s Emma and Regina. Regina was immediately threatened by the arrival of her adopted son , Henry’s, birth-mother, and the two have been rivals ever since. At first, Regina did her best to get Emma to just leave town, which nearly worked. When Emma got a job as a Sheriff’s deputy and became close with Sheriff Graham, Regina killed him. Emma ran to take Graham’s place as Sheriff and won—with Mr. Gold’s help. Next Regina turned her attention to Mary Margaret, framing her for the murder of Kathryn Nolan, in an attempt to ruin both of her enemies’ lives at once. When that finally failed, Regina tried to poison Emma with the same apple that was once used on her mother, Snow White.
