Judging by the beginning of the story I woud bet that Skye was supposed to get executed as well but it did not happen for some reason :) I wonder if you will continue that story to fix that problem :) maybe some prisoner rebellion?

In my opinion Dinah death was a bit too anticlimactic considering that she is Skye's friend and also painslut.
She got a lots of attention in the beginning but she was not that different from other "prisoners"
