Filming for Pretty Little Liars Season 3, Episode 21: "Out of Sight, Out of Mind" is underway … and off to a “great” start!

PLL writer Jonell Lennon took to Twitter to comment about a great day on set with Shay (Emily), Lucy (Aria) and Troian (Spencer), saying the girls brought their "A game." Shay retweeted Jonell's message, adding, “:) great scene!”

In our minds, a great scene either means something really fun, really scary or really, really sad. Regardless, given any of those scenarios, our question is this: Where’s Hanna (Ashley Benson)?

Could she be "out of sight, out of mind' (as the episode title suggests someone, or something, is)? If that’s the case, then we’re betting the scene was either sad or dramatic.

But hold on. Troian also replied to the Twitter conversation, saying, “you guys are the best to play with and now I am so friggin tired!” That seems to imply that it was either a late night scene, or there was a lot of physical (or emotional) activity.

What do you expect from this “great” scene? And what happened to Hanna? Let us know your thoughts in the comments below!

Don’t miss the next new episode of PLL, the Halloween special, on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
