Really creepy. Personally I think Dark Side Atton is very believable--I would like some inkling of Dark Side Exile's motivation in this, though. If it's all about lust, I don't think his POV would be so shot through with...paranoia, with suspicion, with the mystery he finds appealing.

You write well and viscerally.

Wow...just wow.
This strange relationship of theirs almost made me think that it was a canon ending. lol
But how it was depicted was so believable

wow!
Holy hell, that's awesome
