The final piece, and the close of the story.
Not to spoil anything, but the closing lines held a certain context when this was originally written. Blair was known as someone with the power to warp reality in enclosed spaces with illusions. And her involvement here marks the end of Cain’s struggle.
This is a painful thing for me, as it’s the last part of this story ever written as canon. The group fell apart before anything was ever done, so canonically speaking, this is where Cain’s story “ends”. I’ve since revisited it in other words, AUs, etc. But as far as one coherent narrative goes, this is the final chapter for the story Systematic.
