So, who is the titular lost lass? Is the smart money on the recently cast Tinker Bell, who is said to have a “surprising” connection to either Rumple, Regina, Belle, Baelfire, Charming, Snow White or Emma? Is it Bo the Succubus? (OK, probably not.) Shannon Rutherford…?

Of possible note, with a look at the episode’s writers: While Chambliss’ fingerprints are on a variety of Once scripts, Vazquez tends to gravitate toward those featuring backstory for new-ish characters such as Anton the Giant and Tamara.
