I think there have actually been quite a number of stories that used very similar setups to this one! Sometimes I do wonder if they're reading fanfic ...!

This cliffhanger is really not much compared to last season's, when the whole city was about to be destroyed and I really had NO idea how they were going to get out of it. In this case, the "get out of it" is fairly obvious; I can hardly wait to see it, though!
