IMO it depends on the Purser.
If he's tough as nails during the cabin crew briefing on SEP and Security its a reasonable bet that at least 70% of the crew will perform in an emergency. If he's a weak 'one of the boys' type then the captain's the one who has to get tough with the young'uns (the old'uns don't really need it).
This is because the juniors have never been exposed to the potential dangers of this racket (which is understandable). When emphasising the hazards of even a wisp of smoke from any toilet, one will see the blank looks of ignorance on them when one mentions the Air Canada DC9 incident (which I believe is one of the absolute must-sees of any SEP class whether initial or renewal).
Having to run around doing ETOPS over a dark ocean in the middle of the night I don't want them running around like chickens with their head cut off if a cabin fire erupts. The life they save could be my own!
