Of all the Liars, Emily (Shay Mitchell) might have the most complicated relationship with Ali. She used to be in (unrequited?) love with her bestie, and now that Ali is back in the Pretty Little Liars Season 4 winter season, we have a feeling Em is going to be very conflicted.

So, what can we expect from Emily when the show returns on January 7, 2014? We've gathered all of the biggest spoilers about her right here for your reading pleasure.

Emily's complicated feelings for Ali. In the Halloween episode, Em expressed trepidation about seeing Ali again, and now that we know for sure the mean girl is alive, things aren't going to get easier for her. In fact, the episode synopsis for the winter premiere tells us that “Emily has trouble dealing with how she feels about Alison being alive.” But how does she feel? Is there still love there? Or is it anger? Betrayal? Whatever the case, Em will have to find a way to deal with it, because Ali will work with the Liars this season.

What about Paily? Whatever Em's attitude towards Ali, it certainly doesn't mean an end to her relationship with Paige, at least not quickly. We know 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. So don't be too worried, Paily fans!

Will Emily still have feelings for Ali? Sound off in the comments below!

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