Mary Drake has been confusing us since the first day we met her. Is she an evil manipulator or just misunderstood? Check out this mind-blowing moment, and then tell us if she's at the top of your A.D. suspect list using the PLL Suspect Tracker, brought to you by SIMPLE Mobile.
*sighs* We just don't know whether we should hate her or pity her, and here's why...
In S7E14, we found out that Mary Drake killed Jessica.
And it made us extremely suspicious of her, once again. Like, what kind of person kills their own sister?!
But then in the latest episode of PLL, we got to hear her side of the story.
And we found out that Peter and Jessica were actually planning on killing her.
So Mary intercepted the medication meant to kill her, and used it to kill Jessica instead.
We finally found out why Mary killed her sister.
But then we heard Peter's side of the story too.
He needed to protect his family from a "deranged sociopath" who wanted to shatter their lives.
Which left us...confused.
Mary killed her sister, which is AWFUL and definitely an A.D. move. But we can kind of understand why. Jessica was the main reason Mary ended up at Radley, she took one of her babies and Peter took the other. And after all of that, Mary found out that they were both planning to kill her. Is it any wonder she wanted her sister out of the way?
