OUAT executive producer Adam Horowitz recently tweeted the name of Episode 19, which is "Lacey."

We have to admit we have no idea what this title means, which makes it very intriguing.

Is "Lacey" a person? Is it perhaps the mysterious "her" Greg (Ethan Embry) was calling during Season 2, Episode 12: “In the Name of the Brother”? Is OUAT having a crossover with Dancing With the Stars? (We kid.)

Or are we on the wrong track? Is it talking about something that is lacey, like some sort of fabric or dress?

What do you think this title means? Share your theories in the comments!

Catch the next episode of Once Upon a Time on Sunday, February 10, 2013 at 8 p.m. ET/PT on ABC.
