Pretty Little Liars fans-- Tuesday is an episode you don't want to miss!

Pretty Little Liars has been one of the shows we can't stop watching.. for years now we've grown with the characters, got hurt with the characters, and even fell in love with the characters.

The summer finale was such a shock to all of us when we found out that Spencer's (played by Troian Bellsario) boyfriend (played by Keegan Allen) was part of the A Team that has been terrorizing the girls since the first episode.

According to the cast, and the creator Marlene King, Spencer gets to make the shocking discovery on Tuesday night's episode!

Above are some of the Tweets giving us hints as to what is to happen on Tuesday..

As much as we were wishing Toby was good.. apparently he's the opposite..

Ahhh.. heartbreaking! Our hearts can only imagine what Spencer will feel after she finds out!

Between all of Aria's (played by Lucy Hale) drama with her Dad (played by Chad Lowe) after discovering that her father was the last person to see their friend, Ali, alive... and now add Toby getting found out.. It makes us so nervous yet excited! We can't wait for Tuesday night!

Pretty Little Liars airs Tuesday night at 8pm on ABC Family.
