Ok so Paige is for sure somehow a part of endgame. We realize that obviously Jenna also doesn’t know who AD is and I’m guessing Noel was lost too. I think the person Sarah was scared off was Paige. Paige killed Sarah because she’s crazy and is obsessed with Emily. With this said, Paige is not AD. I think perhaps they went back to the twin theory and AD is the twin of Archer Dunhill (which is why it’s the same initials because sometimes that’s a thing for twins) and they worked on a team until Archer was dead af. Wren being AD is a huge theory so isn’t it possible he’s Archers twin? His name is obviously fake and a lot think he was also a fake Doctor (wonder where archer learned it from)
Now I don’t know why Archer and Wren would be the big bad wolves, so that’s something y'all can work on over the next 7 months.
