Not sure I agree with some of their faves… I think her moments in GE, TND and SF are her strongest, but I do like the 'Christ I miss the Cold War' scene in CR. For me, I'd rank them something like this:
1. GE briefing in her office
2. "Perhaps, but the advantage is I don't have to think with them all the time." - Whole scene
3. "Pump her for information" - whole scene
4. Tennyson
5. "Unlike the American government we don't get our bad news from CNN" - Whole scene
6. M's death
7. "Christ I miss the Cold War!" - scene
