Kezzia was a human colonist living on Gliese 581 D in the far future.
She was a member of the set-up team awoken from stasis in advance to ensure the proper function of the city. Kezzia was responsible for overseeing the pollination of the wheat fields by the Vardies.
When Goodthing told her that her mother and a number of the other colonists had been killed by the Vardies, she desperately warned Kezzia to smile to avoid the same fate. However, Kezzia refused to believe her just as she was seized by an Emojibot. It then summoned a swarm of Vardies that ripped her apart as Goodthing watched in horror before being killed herself.(TV: Smile)
