Looks like we didn't really put the "winter hiatus" behind us completely. "Once Upon A Time Fans" Twitter account is reporting that there will be new episode on the 13th - and then there will be a two week break before the next new episode - scheduled to air on February 3rd.
Bad news #Oncers. Following this Sundays episode, #OUAT will be going on a 2 week break. The show will return on the 3rd February.
