Considering we know Ali's already met Charles and knows his identity, this might spell the reveal of Black Swan or Red Coat. The look on the gals faces are a picture, right? They look shocked to the core.
The gals might look like they are in a Syfy show, but it's clear they are in search of answers. Anyone else willing to bet that this is the vault that is in the building Rhys works in? Either that or A has taken them in a time machine into the future. Also, could Mona be the person in red we saw chasing Ali last week? It would make A LOT of sense since she was nowhere to be seen.
The gals have went all out to impress their significant others. If they went to the school prom they would hands down be the best dressed there. I wonder if Hanna stole her dress. Let's face it, she stole a car a few weeks back.
You think the truth is this big shiny disco ball of purity then go ahead and try it. See what it gets you. Telling the truth to the wrong person at the wrong time is how I ended up where I did. Take it from me you're always better off with a really good lie.
