There's a major spoiler for the 'Pretty Little Liars' finale

Warning: there's some seriously PLL spoilers ahead... 

As the show nears it's official ending, writer and producer for Pretty Little Liars, Marlene King has been dropping spoilers left right and centre and fans just can. not. deal. 

She recently shared a super cryptic pic on her Instagram showcasing the set of show's finale... and it looks like we're all in for one hell of a tragic ending.

The photo shows a blackboard with the following heartbreaking quote: "There are no happy endings. Endings are the saddest part. So just give me a happy middle and a very happy start."

What's even more alarming is that fans have noticed a faint 'A' on the blackboard just to add to the suspense.
