Kryten needs a shave! I really want to try this. But I've resisted downloading Snapchat for years. I really don't want to give in just because there's a Kryten filter The only way I can rationalise it does actually make sense. There likely had to be a more prominent change in them to properly convey that their droid-ness(?) was taking over. Both Craig and Danny started changing too, but Craig was more channelling the David Ross era Kryten.
