All of Once Upon a Time Season 2 has been building to an epic mother-daughter reunion between Cora (Barbara Hershey) and Regina (Lana Parrilla). Fortunately, we don't have to wait much longer: the foes finally face off in Season 2, Episode 12: “In the Name of the Brother.”

In one of the most intriguing sneak peeks of the season, Cora tries to convince Regina to let bygones be bygones. "I love you," she claims. "I've just — I've always shown it in all the wrong ways."

Regina is smart enough to know Cora's particular brand of "love" isn't healthy, but by the end of the clip Cora promises to do "anything" to be "worthy" of her daughter. We're a little afraid Regina will start to buy her reformed act, which we don't trust for a minute.

Watch the riveting scene below.
