I got a local PBS pledge drive after this ep also (and after Professor T), which I thought was spectacularly insensitive. I know I'm not the only person who has watched this show over its four seasons 80% for the incomparable Nicola Walker in this role, and to end this season and her run by prattling on about how YOU make series like this possible, oh please. I just want to quietly mourn the end of an era.
Interesting for a character to die because the family pulled the plug, though. You get that with the occasional American movie (The Descendants comes to mind), but rarely in a TV show,
