Spoiler alert a huge character has left the Pretty Little Liars series.
Mona Vanderwaal who has been haunting the girls for over four seasons was killed off in dramatic fashion in the mid season finale. No need to fret though as the actor who plays Mona, Janel Parrish, declared on Twitter that she was still appear in flashbacks.
Although all eyes will be pointed to Allison as being the killer I am assuming that it is a lot more nefarious knowing how twisted this show has gotten.
The show will return for a Christmas special and then will air the rest of the season in the new year.
