It's time to mark your calendars, Pretty Little Liars fans, because Season 4 officially has a return date! The second half of Season 4 will premiere on Tuesday, January 7 at 8 p.m. ET on ABC Family. 

And if it that wasn't exciting enough, fans will get and extra dose of drama when the PLL saga returns on Tuesday, October 22 for its Halloween episode ("Grave New World"). One of the show's biggest mysteries will finally be answered: Is Ali dead or alive? 

Then, our favorite Liars will return in January 2014 to finish up Season 4 with 12 all-new, action-packed episodes! The winter season kicks off with Episode 14 (“Who’s in the Box?”). And of course, we’ve snagged tons of spoilery details about the highly-anticipated episode.

Despite moving on to PLL’s spin off, Ravenswood, Caleb Rivers (Tyler Blackburn) will be making his (possibly) final appearance during the winter premiere. With Showrunner Marlene King calling the episode’s table read “phenomenal,” and PLL writer Joseph Doughertry  adding that the premiere will be “emotional,” we’re expecting to see quite a few heavy scenes — including Caleb’s tear-jerking exit from the show and his relationship with Hanna Marin (Ashley Benson).

But the episode will be filled with some fun times too! Marlene alluded to the Spoby bear (PLL merch inspired by the Toby and Spencer ‘ship on the show) making its easter egg debut during the episode in Toby (Keegan Allen)’s loft and Keegan Instagrammed a photo of actor Nolan North, which pretty much confirms that Spencer’s dad will be making a return… to “clock block.” And the good times doesn’t stop there!

According to Marlene, we should keep our eyes peeled for an Ezra (Ian Harding) and Aria (Lucy Hale) moment, that may include a cabin house… and sex. Score!

While it sucks we’ll have to wait a few months before watching the jam-packed premiere, we will get to see our characters again during the Summer Season 4 PLL Halloween special, airing Tuesday, October 22 at 8 p.m. with the premiere of Ravenswood airing immediately after!
