On face value Sapphire and Steel are trapped in the café in 'nowhere' forever whilst Silver's fate is unknown. However rather than being trapped by their opponents it seems they have been imprisoned by the higher authorities of their own organisation who resent their 'independence'. When Sapphire looked into their future she saw this fate as 'thousands' of years and not eternity. In adventure 3 Steel observes that it would be better if 'operatives' were in place before time crises erupted rather than being dispatched when they had already occurred but Sapphire points out that no one would volunteer to wait for hundreds of years, including him. It is possible that they have actually been put on ice for just such an occasion.
