Well if its a third sister, it's got to be Tabitha Clark, she looks like Ali and what if she was adopted and she "knows" the girls secrets.

Theory Time:

Ali escaped the fire from Spencer's Barn while running away she noticed Tabitha Clark walking and they look excactly alike but before she could confront her she hopped in to her car and drove away but leaving her I.D. behind.

She researched her and finally found out she was adopted and survived an industrial fire making her the perfect "Ali" for the girls. Tabitha and Ali meet and Ali told her everything and wanted to help her new found sister to get revenge. But sadly she died (this was Ali's plan all along and she even probably laughed at it cuz she thinked the girls killed Courtney a second time) and this made the perfect tormentor for the girls cuz they killed her...

What u guys think.....
