I’m not sure if i’m just late to the party but, this is Mona. In the 2 minute preview, a redcape walks by, and Aria says “guys, I don’t think we’re alone in here aymore”. Then it cuts out, in this sneak peak, the redcape above leads them to a secure area, and then the sneak peak cuts out. This isn’t Redcoat. It’s Mona. (Look at the hair)
anyways Redcoat is being revealed later, in a different scene and location.
At first I thought, maybe Mona was Redcoat, aka the ally, but i’m not so sure.
Whether the shock Janel is talking about above is the shock of a “fake” reveal, or something more. I’m not sure. perhaps Mona is playing both sides.
Maybe she’s been “helping” Charles, but one thing’s for sure she’ll lead them to the answers in the ‘A lair’ in the 2nd picture above. If she is double crossing Charles it would explain why Mona’s been so suspicious, and I mean with how she’s been getting caught by the girls. At the lab, failing Lesli, a lot of people think she did that all on purpose. She’s more intelligent than what she’s come across lately and I think that could be the potential answer.
Anyways moral of the post, the first reveal we’re going to get will just be Mona explaining how she’s still involved.
