I read this on TVOvermind.com: When Once Upon a Time returns from hiatus on April 22, expect to explore the theme of fathers-and-sons for a few episodes. We know that episode will focus on Rumpelstiltskin and his son (view photos) and now we know that the April 29 episode, titled “The Stranger”, will also feature Geppetto and his son.
The fact that the show will explore more than one father-son relationship and is devoting two separate episodes to it, further adds proof to the fact that clearly, the episode we will see when we get from hiatus will be about Rumpel/Baelfire and the following episode will be solely about Pinocchio/Geppetto. See, I knew the reason why the episodes were back to back was a red-herring 🙂
