He is extremely self conscious of his own superiority and he finds it distressing to deal with the lower castes, since it reminds him of his physical inadequacies. He orders some Deltas to push his helicopter out onto the roof, but he does this with an arrogant tone.

He is upset by the power which Lenina seems to have over his emotions. He thinks about how the good intentions of Benito Hoover and Lenina make him suffer and feel even worse.

Then they go to play some Obstacle Golf.Back to Bernard, who is walking across the roof with downcast eyes, guiltily and lonely, as if he were being pursued.

(OK, we get it, hypnopaedia works.) She adds that she's glad she's not a Gamma (which is how we know that her wearing green is not an indication of caste).

Looking below her, Lenina remarks that khaki is a horrible color.

Cut to Lenina, who takes off with Henry Foster in his helicopter.

Then he eats some sex-hormone chewing-gum and leaves.

Anyway, Benito remarks on how Lenina is fun to have sex with.

Bernard is left to hang with Benito Hoover, who is so good-natured he could almost get through life without doping himself up all the time with soma.

Lenina departs while quite untactfully announcing her date with Henry.

Lenina and Bernard both depart at the roof, where helicopters are coming and going.

We catch a glimpse of the elevator man, an 'Epsilon-Minus-Semi-Moron' whose only happiness in life is the moment when the elevator gets to the roof, so that he can go, 'Ah! The roof!'.

Bernard blushes and doesn't want to talk about it in public.

Bernard is in the elevator, and she makes a big deal out of publicly discussing their plans for a date.On her way out of the building, Lenina shares an elevator with many Alpha males, most of whom she's slept with.
