I'm with you up to 4x19. The villian centric episodes are obvious, as is the Robin Centric (4x17).

Here's my thoughts on the rest of the stories, based on what we know so far.

4x13 was the reveal that David and Snow did SOMETHING that caused Maleficent to lose her baby (It did not die, I like the choice of words by the writers).

4x16 will be reveal the plan that Snow and David put in place to try and insure Emma stays a hero, and it's going to show that plan unravelling. (Hence the title "Best Laid Plans").

4x19 will be another Emma and Lily centric. I think we will see them meeting again the LWM, probably not long after Emma runs away from Ingrid. Unfortunately, there are a lot of hurt feelings, and Emma is not very trusting, and they end up parting ways again. This episode also has Adult Lily entering Storybrooke. (Maybe even brought by Regina and Emma, since we know that they are taking a road trip somewhere around this time)

4x20 - This one could be multiple flashbacks. 1 with Regina and Cora, One showing Maleficent giving Birth to Lily (this may be where the big reval finally occurs), Maybe even another visit back to Snow Giving Birth to Emma, with some detail that was not included in the pilot.

4x21 and 4x22 are purely random guesses, since we have not had any specific information released on them yet. But I think both stories will need to be told to finish out the current season, and they can occur in either order, this is my guess at the most logical.

4x21 - Some sort of Will Flashback, specifically to the events that happened in Wonderland, and how he ended up seperated from Ana. (Hopefully they will be able to get Emma Rigby to Guest Star as the Red Queen).

4x22 - Flashback on the Sorcerer (including a reveal of who He/She is), and whatever setup is needed for Season 5.
