We're constantly looking for clues about what's coming up next on Pretty Little Liars, and what better source of spoiler-y info than the promos themselves? We've taken a close look at the preview for Season 3, Episode 22: "Will the Circle Be Unbroken?" (March 5) and there's a lot of exciting stuff going on.

Here are the most important things we've gathered from our frame-by-frame analysis:

Spencer in Radley. The promo confirms that Spencer (Troian Bellisario) is stuck in Radley. White dressing gown, ratty hair, crazy eyes — she's rocking mental institution chic like nobody's business.

Mona in control. Mona (Janel Parrish), meanwhile, is cool as a cucumber, using makeup mirrors to spy on the Liars (:04) and messing with Spencer (the whole promo), like a regular super-stalker.

Spencer vs. Mona. Speaking of Mona messing with Spencer, it looks like we'll definitely get a confrontation between these enemies. At :10 Spencer demands from Mona, "Why did you kill Toby?" and later Mona tells her "I have answers to questions you haven't even thought of." And the promo ends with Mona declaring to Spence, "You need me."
 
A Mona flashback. Speaking of Spencer and Mona, it looks like we'll get a flashback about them (as seen starting at :17).  

Joker card. What's with the joker card Spencer is holding at :15?

"A" threatens Hanna. At :12 we see Hanna (Ashley Benson) hold up her phone to Aria (Lucy Hale) and Emily (Shay Mitchell). "A" has sent her a pic (or maybe video) of her mom and Wilden (Bryce Johnson) from the night Ashley hit Wilden. Sounds like sinking the cop car wasn't the end of that story.

"A" keeps the creep up. At :16 we see "A" throwing open some curtains in a dramatic way.
