Do you think they should bring back the moon robot?
Logically, it shut down a few minutes after W&G left and has been rotting there since. But I think that with it being not evil and having sympathetic, harmless aspirations, it deserves better than living life a few coin-operated minutes at a time.
I'd just like to see it brought back to Earth, given a new power source, and live its dreams of exploring the planet. You could still keep it mute, its backstory unexplained, and have conflict from its sense of order acting up at some small offense.
