And maybe what marlene meant by the show "coming full circle" means its going to come back to the facr that the whole NAT club situation was sketchy af. Theres always been more than one group; Mona's group which is the original A team, and the NAT. Although we find out Mona's motive (as well as cece's) we never actually found out any info as to what the NAT club was actually doing and why. Jason said it seemed like they were filming the videos for someone else.. is that someone else A.D?
I’m currently re-watching the series and it seems like Ian was behind it all. He was obsessed with Ali and so he was filming her because he knew he couldn’t have her. It probably will be as simple as that, but I love the idea that AD was behind the filming of the girls. That would be an ideal explanation because it shows that AD has been obsessed with these girls since forever, and I think that’s so creepy, and so twisted, and so I love it!
