We thought we knew everything about the quasi-romantic relationship between Emily (Shay Mitchell) and Alison (Sasha Pieterse), but we were wrong! In the Pretty Little Liars winter premiere, the “intimate details” of their past will be revealed.

According to E! Online, Emison shippers are in for one heck of “a rollercoaster ride of emotions” in Season 4, Episode 14 (“Who’s in the Box?”): “From disbelief to frustration and a whole lotta anger, we'll see Emily tackle her feelings about Alison's return with ferocity and strength. Oh and did we mention that she reveals intimate details of her past with Ali to Paige?” Wowza! Will we be able to handle the Emison/Paily maelstrom of feels? (Probably.)

This news of an intimate past between Emily and Alison might seem troubling to Paily shippers, but we think the fact that Emily is confiding in Paige is a good sign for the future of their relationship. Though things between Paige and Emily hit a few snags in Season 4A, it sounds like they are back on track in the latter half of the season, even with Alison’s unexpected return from the dead.

We know that there are some "great" Paily moments in Episode 19, the couple shares a scene in Episode 21, and there are plans to keep Paige around in Season 5. And that’s not even bringing in the mention of the Paily sex scene Marlene King promised we would get. Basically, it’s going to take a whole lot more than Ali’s resurrection to break these two apart!

Catch the Pretty Little Liars Season 4 winter premiere on Tuesday, January 7, 2014 at 8 p.m. ET on ABC Family.
