Henry Foster thinks Lenina is acting strangely and advises her to get a V.P.S. treatment (Violent Passion Surrogate). Lenina thinks to herself that she already is too passionate—for John. She wants him, and only him. Fanny is disgusted that Lenina wants only one man, and says that if Lenina wants him she should go take him.
Lenina becomes obsessed with the thing she can't have: John. She finds her passion unpleasant. Fanny can only see the dilemma in World State terms: if you want something, take it. Make yourself happy.
The doorbell rings at the Savage's rooms. It's Lenina. Stunned, he lets her in. She observes he doesn't seem happy to see her. He says he wanted to show himself worthy of her, by doing something noble. She sees no point in that.
In the World State where everyone is conditioned to be happy and always get what they want, the ideas of virtue and nobility have no meaning.
The Savage says he loves her. Lenina is overjoyed. But when he mentions marriage, she doesn't understand and starts kissing him.
The ideas of love and commitment have similarly been sacrificed to happiness.
As the Savage mentally steels himself against giving into lust, Lenina begins taking off her clothes. He is horrified. When she's naked but for her hat and shoes, he screams at her to get out of his sight or he'll kill her. She runs, terrified, and locks herself in the bathroom. Suddenly the phone rings. John answers it, exclaims "Oh my god!" and runs out.
At this point of Brave New World now refers to John almost exclusively as "the Savage." This is an ironic move, since it's now clear that John is has self-control and mature emotions, while the citizens of the World State are conditioned not to.
