In the Story
One day in the forest, Kells murdered Jack. He told everyone in Tree Village that Jack was killed by a dragon. He asked Nell to marry him, and told her that it was the only way they would be able to afford to pay their taxes. After they were married, Kells started drinking again. He started to beat Nell, and treated Nell's son, Tim, badly.
One day the Covenant Man came to collect taxes. He gave Tim a key, and manipulated him into opening Kells' trunk. Tim found Jack's coin in Kell's trunk. The Covenant man then told Tim how Kells murdered his father Jack. He then showed Tim in a magic bucket how Kells found out that his trunk was opened, and how he thought Nell had done it. Tim witnessed Kells beating Nell so badly that she became blind.
Kells later went into hiding while the village of tree searched for him. Tim later went into the forest to find Maerlyn to get a cure for Nell's blindness. After the Starkblast, Tim returned home and gave his mother the cure, along with Jack's axe. Kells returned to the house and killed the Widow Smack, because he was jealous that she had a fire during the Starkblast. He then saw Tim and tried to strangle him, but Nell killed him with an Axe.
