Kryten, Red Dwarf's on board mechanoid, rescues a female droid - Camille - from a crashed vessel. She's a 4000 series just like him, only a GTi model with realistic toes and a slide-back sunroof head. Kryten finds himself falling in advanced mutual compatibility on the basis of a primary ident (what humans call "love at first sight") only to find that true advanced mutual compatibility never runs in a non-glitch, bug-free way.
