Heh, I just commented 'huh?' to you.

To quote myself: I know we've had some discussion about recurring OCs in fanfic, but I think treating every original universe as a new work could lend itself to further complications.

I don't think it's a huge Insurmountable Issue, but I think saying 'it would make no difference at all, and there's no chance anything we haven't counted on might come up!' is a bit naive.
