Doctor Who 4.13 Journey's End

This will probably not be my last post on the episode, or the season, or several themes and characters of same (season 4 = my favourite season of New Who, bar none), but I'm leaving for Bali tonight, courtesy of the Aged Parents, so I'm getting this first review done before I possibly (don't know yet) lose internet access for the next two weeks.
