Cora was bating Snow, she want’s her bent on vengance. I don’t think the heart will be Cora’s. I’m thinking it’s a plant & will be Archie’s. Cora did kidnap him after all. I think Snow crushing a heart with malicous intent is will darken her heart regaurdless of who’s it is. Which is what Cora really wants. To top that all off it’s Archie not only did Snow go against her conscience but she would kill a “conscience”.
