Oh, Paige. Paige is allegedly in California, but haven't heard so much as a peep from her since she disappeared. Seems pretty shifty, since she was so involved in the Liars' lives before.
Paige hates Ali. Remember how Ali used to call her "Pigskin"? Remember how Paige tried to drown Emily? We have a feeling Paige isn't as innocent as she looks.
She has a knack for sticking her nose where it doesn't belong. Remember how she leaves a note for the police, telling them that Ali is alive and where they can find her? Like, come on!
Why She's Not Red Coat:
You know, we have to say: we really do believe Paige loves Emily, regardless of what they've been through together. We just can't imagine Paige participating in a huge scheme that would result in Emily's harm.
If Paige moved away, there's a chance she's just gone. People move on. People fall out of touch. Sh*t happens.
