I am happy to share some behind the scenes photos of Once Upon A Time Season 4!! They feature Captain Swan on th estreets of Stroybrooke. In addition, I have some spoilery scoop to share about Queen Elsa and Rumple's past. In season 4 fans will flashback to Elsa's Arendelle and find out how she became a prisoner of Rumplestiltskin. Sources are also revealing that it won't be long before we will see just how Anna and Kristoff fit into the landscape.
