Pretty Little Liars Season 4B Spoilers: 12 Things We Learn in the Promo (VIDEO)

Now that we know for sure Ali is alive, the Pretty Little Liars Season 4 winter season can't get here fast enough. Sasha Pieterse is one of our favorite actresses on the show, and throwing Ali back into the mix should make the fight against "A" more exciting than ever.

The new promo for the winter season certainly makes it look like it will be overflowing with thrills. From confrontations with Ali to Ezra and Mona having a little chat (awesome!), every moment in this preview is one we want to see.

So, what does the promo tell us about next season? We've taken a close at what it reveals.

Yes, the Liars will see Ali again. Ali popped up in the flesh at the end of the Halloween episode, but she skedaddled before she could give many answers. If you were worried that's the last we'll see of her for a while, never fear: this promo begins with Emily talking to her. More Ali means more drama, and we couldn't be happier to have her back.

Who is Ali hiding from? Emily begs Ali to reveal who she's hiding from, but Ali admits, "I thought I knew, but I was wrong." Later, Spencer ponders that there's "someone Ali is so afraid of, she can't come back."

Em in church. At :06 we see Emily, apparently alone in the church. Yeah, 'cause that always ends so well for the Liars.

More night drama. At :31 we see all four Liars out at night. There's a flash of thunder, and we see that they are by a car that has its trunk open.

Running to catch Ali. Want to know more about Ali and Emily? Well, at :07 we see Emily running to catch her old BFF as Ali descends in an elevator.

A broken window and an empty room. At :09 we see Spence examine what looks like a broken window. Is it a clue about where Ali is hiding? Or maybe a hint about "A"? Or did Spencer break it herself? In the next shot we see all four Liars standing in an empty room, and Spence is clutching a hockey stick next to the window. Whatever the Liars expected to find in the room, they're "too late," as "A" tells them in a message on the door at :10.

Ezra and Mona meet. Is Ezra really "A"? If so, does Mona know? Either way, these two suspicious characters definitely have a sit down together next season, as we see at :11. They're talking over coffee, and Ezra tells Mona, "Fear can be a very good thing." That certainly sounds like something "A" would think.

Hanna's bad dentist encounter. At :13 we see Hanna meet a bad fate at what looks to be a dentist's office, and then at :18 we see Spencer pull an "A" message out of Hanna's tooth. Ew. Ew ew ew.

The Liars arm themselves? At :14 we see Spencer and Aria grab heavy tools (like a shovel) in a shed. Are they arming themselves?

Hi Caleb! Caleb does return from Ravenswood for at least a brief time, and at :16 we see Hanna yelling at him, "Tell me what happened!" Our guess? She wants to know what's going down with him in Ravenswood, which will take more than a little explaining.

Emily. At :17 we see Emily (at least, we're pretty sure it's Emily" freak out when Spencer tries to touch her.

Aria gets rough. At :17 Aria grabs Maggie's arm roughly. She does not look happy. We wonder what she has to say to Ezra's fake baby mama.

Check out the promo for yourself below, and let us know what clues you see!
