Pretty Little Liars is about to make a big move that could affect the rest of the season.

On Tuesday's episode of the ABC Family drama, the identity of the Rosewood betrayer will be revealed as part of the "A" team. The cable network launched a suspect tracker earlier this month to help viewers keep track of the field of 12 suspects. A new web series, Pretty Dirty Secrets, will also debut during the finale and go on through October when the Halloween episode is slated to air.
