The ABC Family series isn't set to return until Jan. 6, but series creator Marlene King is already teasing the season 5 finale. King took to Instagram on Saturday to give fans a cryptic hint for "Welcome to the Dollhouse."

"PLL starts January 6 and the finale ends here. Many clues to be found in this song," King wrote. "#PatsyCline #WalkinAfterMidnight #ForReal."

Check out the Walkin' After Midnight lyrics below, and tell us what you think will happen in the season 5 finale.

"I go out walkin' after midnight
Out in the moonlight
Just like we used to do
I'm always walkin' after midnight searchin' for you

I walk for miles along the highway
Well, that's just my way
Of sayin' I love you
I'm always walkin' after midnight, searchin' for you

I stop to see a weepin' willow
Cryin' on his pillow
Maybe he's cryin' for me
And as the skies turn gloomy
Night winds whisper to me
I'm lonesome as I can be."
