Kim has had a crush on Jared for a while, sitting next to him in class every day at school for a year, and also going to the extent of writing her name with his surname on to her diary. One day, after Jared phased, he imprinted on Kim in history class, nicely reciprocating her crush. Jacob explains how Jared never took notice in her until he looked at her for the first time after he changed into a shape-shifter, and he never looked away. Being too happy to see his newfound attention to her, she took his shape-shifter powers and duties in stride.
Kim is introduced in Eclipse at a Quileute bonfire, which is also a council meeting for all the members involved, with Bella Swan as the exception. When Jacob Black first explains her story to Bella, she wonders why Jared would say something about his "soulmate" to Jacob, but he explains that Jared cannot help it, because of the pack's ability to read each other's minds.
Kim makes a brief appearance in the film adaptation of Breaking Dawn when she appears on the beach with Jared and the other imprinted couples, including Sam and Emily, Paul and Rachel, and Quil and Claire. While they hang out, they are being watched by Jacob, Embry, Seth and Leah.
She has a wide face, mostly cheekbones, with eyes too small to balance them out. Her nose and mouth were both too broad for traditional beauty. Her flat black hair was thin and wispy in the wind. Bella notices her smooth skin that 'looked like russet-colored silk in the firelight', the perfect shape of her lips and 'how white her teeth were against them' and how her long eyelashes brushed her cheek when she looked down.
Personality and traits
When Bella first sees Kim, she describes her as being "a nice girl, a little shy and a bit plain". After watching Jared looking at her, Bella notices how truly beautiful she is, and not plain at all. Watching them, she realizes just how strongly imprinting affects shape-shifters.
