How Spooks Should End?

[tyme4t]

As they say - all good things must come to an end - so for [spooks] I think it will involve an "ending" of Harry as we all know and love him - how 'bout a promotion to DG instead of retirement or death?
As long as somehow it indicates that Section D continues as it always has...remember when "Cheers" ended - Sam simply said "We're closed." We know the gang at Cheers came the next day when he opened...
