Alison (Sasha Pieterse) and Emily's (Shay Mitchell) complex relationship has been at the heart of the first few episodes of the Pretty Little Liars Season 4 winter season. So for today's Flashback Friday video, we want to revisit one of the most memorable Ali and Emily flashbacks: the one where they fantasize about traveling to France.

In this clip, Ali and Em are supposed to be studying for French class, but Ali is more interested in discussing a dream vacation that goes from the south of France up to Paris.

"You'd look so good on top of the Eiffel Tower, wind in your hair," Ali says, before moving over to where Em is and letting their hands brush.

"How long are we going away for?" Emily asks.

"How about forever?" Ali replies with a smile.

It's one of those moments where it really feels like Ali might care for Emily. Is this moment only part of Ali's twisted game, another way to keep Em under her thumb? Or is this Ali genuinely dreaming of escaping the world she's created for herself?

Check it out for yourself below.

What do you think: Was Ali just using Emily, or did she really have feelings for her? Let us know in the comments below!
