That is true.
We did see this storyline coming from the very beginning, but it actually seems well plotted out unlike the Cyrus storyline. If they just build it up to the right time, and not drag it out longer than they should, the big reveal and payoff will be great to see.
That's very cool actually! I knew that there was supposed to be a fourth friend who was still living in New York (which eventually became became Cassie), but was dropped since they didn't want to do dual action in Savannah / New York. I had no idea she was cast and even shot scenes.
