You forgot the VOY staple:
- Seven causes a problem/situation for the rest of the crew,
- Seven resolves a problem/situation for the rest of the crew,
- Seven "learns" something about humanity from Janeway/EMH,
- A combination of either two/all three of these elements.
And then from TNG:
Worf recommends a intelligent course of action ... which Picard immediately ignores.
Troi states a observation ... which is blindingly obvious.
