The Pretty Little Liars Season 4 winter season opened with an episode that left us more confused about Ezra's real motivation than ever, but based on the preview for Season 4, Episode 15, "Love ShAck, Baby," we'll get to see Mr. Shady in action next week.

What else can we expect from the episode? We've rounded up the biggest spoilers about it right here so you can prepare for all the action.

What's in the diary? The winter premiere ended with Hanna letting the other Liars know she swiped Ali's diary from "A"'s lair, but she also hinted that Ali had some not-so-nice things to say about her friends in the journal's pages. We should learn more about that this week. In fact, most of the official synopsis of the episode is all about the diary:

Now that Hanna has shared with Aria, Emily and Spencer that she has Ali’s diary, the girls hope it can shed light on their many questions. But with the diary full of stories that have been coded to cover the truth, each girl must take a turn to figure out which stories are about them. Hopefully when they are through they will find the story that could finally give them answers to who has been going after Ali. But with each story more personal than the last, do Aria, Emily, Hanna and Spencer really want to admit which story is about them? 

We know that this season will unearth a secret Spencer has been keeping from her friends. Could that truth, whatever it is, be hidden in this diary? That's certainly a possibility, though obviously Ali's words are not the only way Spence's secret could get out.

What's up with Spencer's dad? Speaking of Spencer, her father came back in a big way in the winter premiere, and it sounds like we can expect more shady behavior from him in the next episode, since the official synopsis also explains that "Spencer is suspicious of her father's latest interaction with Mrs. DiLaurentis."

"Real surprises." According to director Norman Buckley, we can expect some "real surprises" this week. Hopefully they have something to do with Ezra!

Heartbreaking times for Hanna. Apparently Ashley Benson is totally going to make us cry this week, but why? Is it from the aftermath of the Haleb breakup? Or maybe something to do with the hefty Hanna flashback that will be featured? Our guess is the latter.

The Liars are stranded. The Liars will be "stranded" this week and, based on the promo, we're guessing that's a reference to the girls getting stuck in Ezra's creepy cabin while "A" is there!

We'll see Ali! Thanks to an exclusive behind-the-scenes photo from director Norman Buckley, we know that Alison will be in this episode. But is it present day Ali, or flashback Ali? Either way, we're just happy to get another taste of Rosewood's biggest mean girl. She was missed in the premiere!

Aria and Ezra interact. It might only be in a classroom setting, but at least we'll have at least one Aria and Ezra scene this week.
