WATCH: Pretty Little Liars FAtal Finale Sneak Peek - Emily Asks, 'Is Ali A?'

Happy FAtal Finale day! It's Pretty Little Liars' summer finale, and there are so many questions to be answered. First off, someone is going to die and we're seriously hoping it's not another one of Emily's (Shay Mitchell) girlfriends, because that would just be too much. But who will it be? The other big question on the Liars' minds is whether or not Alison is A. In this scary little sneak peek Emily tries to do some reconnaissance, but it's tough to pull anything over on the hyper-vigilant Ali. 

Watch the terrifying little exchange below.
