The conditioning of Linda is totally different from what exists on the Reservation. When Linda , who has never been made to do anything manual, breaks a loom on which she is supposed to weave, the women are angry with her and push her.
Pope is a man who stays with Linda, and because she has been conditioned to believe that "everyone belongs to everyone else," she engages in sexual acts with this man, drinking mescal, which numbs her senses like soma, but it gives her a headache the next day. When Linda sleeps with other men, the women break in and whip her, much to her incomprehension and amazement. She tells John,
"They say those men are their men."
Linda misses "The Other Place" where there were games to play, delicious things to eat and drink, and lights came on automatically. Everybody is happy; at least, they are not sad or angry. There is tecnology, babies in bottles, clean, sterile things. In short, the world that Linda has left is the antithesis of the reservation. Everything is mechanical and programmed; nothing is spontaneous or natural and based upon imagination. Linda knows nothing about the world of the earth and sun and stars and mothers and fathers and children; she is from another world, the New World. As a product of the Central London Hatchery and Conditioning Centre, Linda simply cannot relate to what she has not been conditioned.
Looking only at Chapter 8, the thing that Linda has a problem with is the Savages' attitude towards sex.
In this chapter, we see that Linda continues to behave in ways that are acceptable in the civilization that she came from. She has sex with lots of different men. This is, of course, not acceptable to people in the more traditional savage society.
Linda's inability to adapt to the more traditional sexual mores causes a great deal of trouble for her and for her son John. They are both sort of shunned because she is having sex with other women's husbands.
