[spoilers] Wonderful ways to bring characters back

[Nitrus]

OK brace yourself:

Ruth comes back to save Harry & in the process contacts Tom for help, he uses contacts in the security industry to contact Zoe, they all meet in Moscow & try to track down Harry. Meanwhile Zaf has escaped his captors (who never killed him) & he is on the run in China, where he stumbles across Adam, who faked his death to escape Spook life. Zaf has found out about Harry from a Russian contact in China, so he tells Adam & they both leap into action and goto Moscow. In Moscow Tom, Zoe & Ruth have been following leads about the whereabouts of Harry, they find out that a mysterious hacker may hold the answer. They storm his flat only to find COLIN! Who made a deal with the MI6 men to let him go & fake his death. They ALL eventually meet outside the kremlin and aggregate their collective intelligence. They discover that all intelligence leads back to one word "RAREFACTION". This is the codename of deep cover agent based in Moscow, who is reportedly behind the the capture of Harry, they track the agent down to a dingy flat in Moscow, where they kick down the door to find Harry tied up, and Fiona Carter standing over him with a gun. SHOCK!

^That's sorta how I'd like it to happen
