 When the stern of the ship is vertical, Chief Baker Joughin  (Liam Tuohy (qv), in white) is drinking from a flask. Joughin was  one of few to survive the freezing water, allegedly due to the  alcohol (but this is disputed as unlikely since alcohol is known to  accelerate hypothermia, not to help resist cold). The scene was  added after Liam showed the flask to James Cameron (I) (qv)  explaining that it was a family heirloom as old as the Titanic  itself.
