On top of that, it also turns out Paige's crush on Emily has gone on for way longer than we initially thought, making it more likely that she may have killed Maya (Bianca Lawson) in a fit of jealousy. And, of course, we know she saw Emily "that night." Who knows if she's telling the whole truth about what happened.
But do these clues really mean Paige is part of the "A" team? The evidence remains mostly circumstantial, and it's possible "A" planted the earring. It would be far from the first time "A" tried to frame someone for something they didn't do.
