how does lenina view bernards reaction to his surprise?

After work, Lenina and Bernard Marx share a crowded elevator heading to the roof. In front of everyone, she tells Bernard that she will go on a date with him. She offers to take a weeklong trip to New Mexico if Bernard still wants to have her. The public display embarrasses Marx, who would prefer to talk it over in private. Lenina laughs at his awkwardness and then takes off with Henry Foster in a helicopter.
