Game over, Charles! Pretty Little Liars is about to finally answer the series' six-year-long question: Who is A?

On Tuesday's finale, Alison, Aria, Emily, Hanna and Spencer will come face to face with the person who tormented the group for years, killed their friends and foes, kidnapped them and pretty much ruined everyone's lives. While we've had a very long time to prepare for this moment, we have absolutely no idea how we'll handle it. Luckily for us, star Shay Mitchell and executive producer Marlene King gave us their best predictions for how fans will react! Spoiler alert: They get really into it and it's pretty awesome.

Check out the video above and share your best theory for Charles below!

The Pretty Little Liars finale airs on Tuesday at 8/7c on ABC Family.
