Oh! I have just finished watching Mysterious Skin today and this is the world's biggest YES!!

It stands on its own just on Inception canon, but imagining Neil's past (or something like it) as part of this character just adds so much depth. I love the delicacy of your references to it too, no specific information is imparted and Arthur retains his mystery.

Are you still considering writing more? If begging would help my cause, just let me know!
