We're constantly looking for clues about what's coming up next on Pretty Little Liars, and what better source of info than the promos themselves?

We've taken a close look at the preview for Season 3, Episode 21: "Out of Sight, Out of Mind" (February 26)  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:

Aria in tears. Why is Aria (Lucy Hale) in tears at :03? Is it about Ezra (Ian Harding)?

Spencer fights back. Spencer (Troian Bellisario) goes into full-on badass mode as she threatens Mona (Janel Parrish) at The Brew: "If you so much as touch a hair on their heads, I will make you very sorry

Deep sympathies. At :08 we see the bouquet "A" was putting together at the end of Episode 20, which has a ribbon on it that says "My deepest sympathies." It looks like the person receiving it is Spencer, and the sneak peek photo above seems to confirm that.
 
A threat. Well, we know this is a threat: "Someone close to you will pay for your loose lips - A." As we see at :10, that message is written on a fancy card, and we're thinking it's the message that goes with the bouquet. We know Spencer tells the Liars about Toby (Keegan Allen) this week, so we assume this is "A"'s response.

Spencer running down the stairs. At :10 we see Spencer crouch on what looks like The Brew's stairs. She seems to see something, and starts running down the stairs. Is she trying to catch Toby? Someone else?

In the woods. At :11 we see what looks like Hanna (Ashley Benson) and Aria standing in the woods. We could be wrong about who it is, though.

The girl in red. Someone — it would appear to be Emily (Shay Mitchell) — spots the girl in red in their rearview window at :11-12.

Emily gets a message. At :17 we see a red envelope (or bag?) with the word "Emily" on it. Based on the next shot, it looks like it is left in in Em's car, and potentially that her car window has been broken. Our guess: She sees the woman in red, goes chasing after her, comes back to find this message in the car.


More cops for Hanna? At :12 we see Hanna open a door, and it looks like there are police car lights flashing. A follow up to her mom hitting Wilden (Bryce Johnson)?

A cage. Someone is locking a cage at :14.

Spencer in the woods. The promo ends with someone running through the woods, and then Spencer in a clearing.
