I've actually read some great 'and then Rodney rescues John and they live happily ever after' fics for this episode (which, God, really needs Rodney to be rewritten as a little nicer, since the alternative is John saving them and being left to bleed to death in the desert). It's just starting to freak me out that *no-one else has noticed* the wedding ring, considering how observant fandom generally is.
