Kate offers support to Sawyer, while he is mourning for Juliet. The two then continue to be attracted to each other, but for the remander of what is shown, the two never act as a couple anymore.
In the final episode, Kate gets off the island, along with five other people, including Sawyer. It is unknown what happened to her after she left, but it is possible that she resumed her relationship with Sawyer.
In the afterlife, the two reunite, but they do not sit together in the church scene, as Sawyer sits with Juliet, and Kate sits with Jack.
