I'm SO pleased you liked the ending - lots of people didn't - because I did feel it did justice to the nature of the show, at least in series 1 and 2. Links? Try these, which I've copied from my LJ:

Shattered (http://www.livejournal.com/users/tigertrapped/5783.html)
Everyone screws with the new recruit. In two parts. Part 1 is PG-13 for language; Part 2 is NC-17 for what you might expect
Resignation (http://www.livejournal.com/users/tigertrapped/7866.html)
The recruit kicks back. PG-13 (for bad language)

Happy reading, and thanks again for being so generous with the feedback. I'm a very happy Tiger.
