We already know two people who have survived after their hearts have been pulled: Graham and Daniel (although Daniel’s heart was immediately crushed, which is what killed him). I’m thinking the heart is actually Kathryn’s, which will throw the entire case onto Regina—or get it thrown out.
This is what I found freaky…the heart has already testep POSITIVE for kathryn…It is going to blow the lid off of who Regina REALLY is, and in my opinion start the wheel turning for everyone to get their memories back
