ok, this is a pretty rushed version, just to nail down what id like to see happen, and have a little bit of dialouge in it too, i'll make it much better, but what do you think so far?
If there are any objections to this marriage, speak now; or forever hold your peace...
[camera fixes fans round martin, sues, and finally macs faces, who all twitch a little]
Vicar: Do you take this man to be your lawfully wedded husband?
caroline: I do
vicar: Gay secretan do you take this woman to be your lawfully wedded wife?
guy: its GUY secretan you KNOB!!!
vicar: ah, sorry GUY secretan [winks] - do you take this woman to be your lawfully wedded wife?
guy: [girtted teeth] i do
vicar: [jubilantly] i now pronounce you - man and wife!
[wedding music plays - the kinks: you really got me. guy+caroline walk down the isle, and mac stares after them, makes to chase after them, but holds back, turns around, and sinks his head into his arms]
[outside the church, guy and caroline walk towards the wedding car]
guy: [under his breathe] do ya like that ginger man... i win, hippy tosspot...
caroline: what?
guy: ermmmm... i love you?
[they step into the wedding car. sighs of relief from both guy and caroline that they finally made it]
[shot of the driver; its martin! who has decided to kidnap them as he never felt caroline gave him a chance]
caroline:well, despite all the setbacks, we finally made it guy... for the first time in my life, i feel normal, everthing has gon to plan! no hicups or ANYTHING!

caroline: [SCREAMS]

[camera pans slowly to bottom of ambulance]
[sue white, dressed in all black, holding a spanner.....]

[camera pans away from the car, to the sound of cackling sue, and the music they played in the real ending, whatever that was...]
one final surprise.....
a camera shot of a letter to mac on his dressing room table that hes decided not to bring to wedding..... its basicly a letter from the doctor saying hes not really dying blah de blah de blah, just read how you want mac to survive, [as we all do!!!] so i add this little scene at the end!
