Brave New World Chapter 13

“A V.P.S. treatment indeed! She would have laughed, if she hadn't been on the point of crying. As though she hadn't got enough V. P. of her own! She sighed profoundly as she refilled her syringe. "John," she murmured to herself, "John …" Then "My Ford," she wondered, "have I given this one its sleeping sickness injection, or haven't I?" She simply couldn't remember. In the end, she decided not to run the risk of letting it have a second dose, and moved down the line to the next bottle.”

John thinks Lenina was acting strange in this quote.

“An hour later, in the Changing Room, Fanny was energetically protesting. "But it's absurd to let yourself get into a state like this. Simply absurd," she repeated. "And what about? A man–one man."
"But he's the one I want."

Lenina feels passionate that her heart belongs to John. She wants to have him, only him.

"Don't think of him."
"I can't help it."
"Take soma, then."
"I do."
"Well, go on."
"But in the intervals I still like him. I shall always like him."
"Well, if that's the case," said Fanny, with decision, "why don't you just go and take him. Whether he wants it or no."

Fanny was getting jealous of Lenina saying that she needs John, but Fanny wants Lenina to take John for herself.

“The bell rang, and the Savage, who was impatiently hoping that Helmholtz would come that afternoon (for having at last made up his mind to talk to Helmholtz about Lenina, he could not bear to postpone his confidences a moment longer), jumped up and ran to the door.
"I had a premonition it was you, Helmholtz," he shouted as he opened.
On the threshold, in a white acetate-satin sailor suit, and with a round white cap rakishly tilted over her left ear, stood Lenina.
"Oh!" said the Savage, as though some one had struck him a heavy blow.”

This quote explains that John was hoping that Helmholtz will come over to his house, but it turns out that Lenina was in front of the door instead of Helmholtz which cause John to be in shock.

“Half a gramme had been enough to make Lenina forget her fears and her embarrassments. "Hullo, John," she said, smiling, and walked past him into the room. Automatically he closed the door and followed her. Lenina sat down. There was a long silence.
"You don't seem very glad to see me, John," she said at last.
"Not glad?" The Savage looked at her reproachfully; then suddenly fell on his knees before her and, taking Lenina's hand, reverently kissed it. "Not glad? Oh, if you only knew," he whispered and, venturing to raise his eyes to her face, "Admired Lenina," he went on, "indeed the top of admiration, worth what's dearest in the world." She smiled at him with a luscious tenderness. "Oh, you so perfect" (she was leaning towards him with parted lips), "so perfect and so peerless are created" (nearer and nearer) "of every creature's best." Still nearer. The Savage suddenly scrambled to his feet. "That's why," he said speaking with averted face, "I wanted to do something first … I mean, to show I was worthy of you. Not that I could ever really be that. But at any rate to show I wasn't absolutely un-worthy. I wanted to do something."

In this quote, John was finally able to speak out to Lenina that he wants to be worthy of her and be with her because he think he was the most beautiful girl that he ever seems, but he doesn’t want to do everything to her bad.

"Why should you think it necessary …" Lenina began, but left the sentence unfinished. There was a note of irritation in her voice. When one has leant forward, nearer and nearer, with parted lips–only to find oneself, quite suddenly, as a clumsy oaf scrambles to his feet, leaning towards nothing at all–well, there is a reason, even with half a gramme of soma circulating in one's blood-stream, a genuine reason for annoyance.”

Lenina was starting to feel annoyed why John would be thinking about her by being worthy.

“Confused, "I'll do anything," he went on, more and more incoherently. "Anything you tell me. There be some sports are painful–you know. But their labour delight in them sets off. That's what I feel. I mean I'd sweep the floor if you wanted."

This is when John confess his love towards Lenina.

"It's like that in Shakespeare too. 'If thou cost break her virgin knot before all sanctimonious ceremonies may with full and holy rite …'

And suddenly her arms were round his neck; he felt her lips soft against his own.”

After John tells his confession to Lenina, she wants to feel real love towards him.

“But when she unbuckled her white patent cartridge belt and hung it carefully over the back of a chair, he began to suspect that he had been mistaken.”

This is when Lenina was starting to take off her clothes, but John is starting to feel terrify of what ya about to happen next.

“The Savage pushed her away with such force that she staggered and fell. "Go," he shouted, standing over her menacingly, "get out of my sight or I'll kill you." He clenched his fists.
Lenina raised her arm to cover her face. "No, please don't, John …"
"Hurry up. Quick!"
One arm still raised, and following his every movement with a terrified eye, she scrambled to her feet and still crouching, still covering her head, made a dash for the bathroom.
The noise of that prodigious slap by which her departure was accelerated was like a pistol shot.”

When Lenina is 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.

"Hullo."
. . . . .
"Yes."
. . . . .
"If I do not usurp myself, I am."
. . . . .
"Yes, didn't you hear me say so? Mr. Savage speaking."
. . . . .
"What? Who's ill? Of course it interests me."
. . . . .
"But is it serious? Is she really bad? I'll go at once …"
. . . . .
"Not in her rooms any more? Where has she been taken?"
. . . . .
"Oh, my God! What's the address?"
. . . . .
"Three Park Lane–is that it? Three? Thanks."

John got a phone call and I think something bad happen to Lenina.
