Not really a pairing I had read before (and I still find calling him 'Green' instead of 'Blue' awkward) but a very well-done fic. Certainly provides a good reason for Red to disappear like that-- I always wondered just why he's stayed up there so long, and why, in Silver, you don't tell his mom where he is after you've beaten him.

Not that I found Red impossible to beat, either, but I digress.
