Who's leaving Who?

Here's a birrova of an exclusive, boys and girls...some excerpts from filming of the new series of Dr Who in February this year. Woohoo!! Featuring David Tennant (the Doc), John Barrowman (the returning Captain Jack Harkness) and Freema Agyeman (new companion Martha Jones). Looks like this could be one of the last scenes from the season's finale episodes, judging by the fact that it ends with Jack walking off and throwing the Dr a very military salute! Or it certainly looks that way...WHO knows.

But...just what are they all saying to one another? What's going on? What is the Dr doing to Jack's hand? And what are the Doc and Martha reacting to at the end, with such shock and hilarity?! (As this was obviously filmed on a fan's camera and from a distance, we can't hear anything that's being said...of course the Beeb would forbid that anyway, the b*ggers).

In which case I am throwing up a little challenge for some of my fellow bloggers. And I'm going to tag Minge, TimeWarden and Samarcand. I'd like all of you to tell me a) what the Dr, Jack and Martha are doing and saying in this scene b) what the end bit is all about. You can even write your own mini-script if you like. The more creative, the better. Please send me your ideas by responding to this post. Cheers guys!

Of course, knowing you boys like I do, I just know I'll get some very "interesting" responses...
