I didn't read the Novelization and I didn't have other quotes in mind.
You mean that when Ripley sees Parker and Lambert and then goes to selfdestruct the spaceship, the Alien comes back to take Lambert ?
By the way, when I first saw the movie longtime ago, I though it was playing with Lambert and she was so afraid she was making these strange noises, I didn't think of a rape.
But if the xeno can impregnate, that doesn't mean it has a sexual interest in her. Even if Scott said something else afterwards, I still like the idea that Lambert could "give birth" to another xeno.
Thanks anyway for your information
