Kayce and Monica never told John that they had another kid after Tate. Kenzie is 5 years old and the younger sister of Tate and the granddaughter of John Dutton. She looks exactly like the Dutton family she looks exactly like Lee and Kayce brown hair big hazel eyes and a but of a smart ass. Kayce went over with Tate and her since him and John had finally mended fences. She was shy she hid behind Kayce's legs. John was pissed that Kayce and Monica never told him about her. Tate went off to go bug Jamie about something while Lee and Kayce went off Lee was most likely going to yell at his little brother for keeping it a secret about her. John scooped her up in his arms looking at her she was definitely a Dutton a perfect little Dutton copy where as Tate looked more like Monica's side of the family. John went and sat on the porch her in his lap she looked at him circously she didn't talk much. John ran a hand through her hair lovingly he was already in love with his little granddaughter. He decided to break the silence and tease her a little. John: Don't talk much do ya? What does a cat got your tongue? he asked smiling at her as he lightly tapped her chin with his pointer finger
