Someone's Dying in the Pretty Little Liars Finale, but Who?!

If Caleb doesn't die, Toby might be the next easiest target. Spencer is clearly the most entangled in this final game, and Toby is the one who's closest to her. There are other reasons Spencer is the one to hurt. She's related to Mary Drake. She smashes the phone that "A.D." provides as part of the final game. She also seems to be the ringleader in the cover up of Archer Dunhill's murder. If "A.D." wanted to hurt Spencer the most, Toby is the target.
