Nothing.

I assume he's isn't dead, because I continue to receive my divs from his first operation.

Also, after some digging, it is true he paid for the first Neptune, here is the link to the receipt:

Order number: 1J4-X705-011676
(which is valid on their site, shows only 'paid')

All that being said, I have no idea where he is, or what he's doing. I can only assume he'll show back up when that Neptune arrives on his doorstep. At least I hope so.
