Paul Lahote and Rachel Black

Paul Lahote and Rachel Black are mentioned to have started a relationship after Paul imprints on her by accident.

Paul Lahote
Paul is a shape-shifter in Sam Uley's pack. He was born in Tacoma, but when his parents divorced, he moved to La Push with his father.

He had his own crowd of friends as a human, so when he started phasing and hung out with Jared and Sam, his distance became slightly suspicious. As a wolf, he sets protecting La Push and the Quileute traditional lands as his job.

Rachel Black
Rachel is the first born child of Billy and Sarah Black, older sister of Rebecca and Jacob Black, as well as sister-in-law of Solomon Finar.

She was devastated by her mother's death, and by the time she graduated from high school, she moved away to attend college. When she graduated in 2006, she went back to La Push to visit her family.

Breaking Dawn
Sometime in between Eclipse and Breaking Dawn - Book 2, Rachel and Paul walked down First Beach alone. When they stumbled across each other, Paul imprinted on her, and later told her everything about their tribe's magic and heritage.

She accepted his explanation and reluctantly decided to stay in La Push for a while to see how their relationship will work out - and hopefully waits for Paul to be able to leave with her someday. Billy is happy to know that she has decided to stay for Paul, though Paul is always at their house, eating their food, taking most of their sofa and using their TV, which annoys them very deeply. However, Paul seems to have gotten a better control of his anger.

There is no mention of their relationship or how they progress after Book 2.
