Talk:The Liars/@comment-4075031-20150813233100

Okay, here is something people need to understand: Mona IS NOT part of 'core group', as Marlene stated it. Mona IS one of the Liars.

It's seriously as simple as that. The 'core group' is a group of five friends from the Pilot - Ali, Aria, Hanna, Spencer and Emily. Mona wasn't, and as much as I would love this, I don't think she will ever be part of that group. In that interview it even sounds like Marlene doesn't have the plan to make her part of that group.

BUT

The 'core group' IS NOT the group of The Liars. The core group - Ali and her friends. The Liars - girls who are A's 'dolls', who are trying to undercover him and were later in the dollhouse. The person doesn't need to be Ali's friend to be the Liar. That person needs to be A's victim. And Mona is since season four, as confirmed by writers.
