I still wondering if Regina has the heart collection at this time. There seems to be too many similarities with the containers of the Queen of Hearts and Regina’s. The flower emblems on the door is the same in Wonderland, FTL, and in Storybrooke. The boxes are the same, including the numbers/letters on the boxes. It always bothered me when Regina first took the heart from the Huntsman, put it in the box and held it up to the wall; she was surprised it didn’t work. In fact I believe she stated as much, more like she acquired the boxes vice creating them. If they are the same boxes then there is a higher probability that the Hatter is after Snow’s Father’s death, but before the Huntsman. That’s assuming the boxes are the same.
