We still have most of the Pretty Little Liars Season 4 summer season to look forward to, but now, thanks to a spoiler from SpoilerTV, we can already look way into the future of Rosewood, with the title of the Pretty Little Liars winter premiere, Season 4, Episode 14.

According to SpoilerTV, Season 4, Episode 14 will be titled "Who's in the Box?"

If this title is accurate, it makes us wonder if there is another cliffhanger mystery headed our way, perhaps at the end of the Halloween special (Season 4, Episode 13). Will we have another "what's in Wilden's trunk" situation? Or will the box in question not show up until the premiere?

The fact that the question is who's in the box is also interesting. Normally boxes aren't person sized. Maybe the "box" here is actually a coffin?

Whatever the case, we can't help but wonder if this title is an intentional reference to the famous scene at the end of the thriller Se7en, which memorably features Brad Pitt shouting, "What's in the box? What's in the f---ing box?!" Given the Pretty Little Liars writers' love of referencing classic cinema, we wouldn't be surprised if this is an intentional nod. Either way, we hope the answer isn't as gruesome as it is in Se7en!
