HIDDEN DETAILS: The episode "Broken Heart" reveals that Merlin's message from "The Bear and the Bow", was recorded in the kitchen of Granny's Diner, and that the Dark One who found Merlin was Hook. If you watch the "recording" in "The Bear and the Bow", you can see the kitchen shelves and lamps behind Merlin, and as Merlin turns his head as he hears the Dark One coming, Hook's silhouette can be seen in the background, behind Merlin's left arm. It matches what is seen when Merlin records the message in this episode.
