Mitch Baker made his first appearance on 12th March 2018 and he is the ex-partner of Karen Taylor and father to two of her children Chantelle and Keegan as well as a daughter Bailey from another relationship.
Mitch suddenly turns on the Square, to the surprise of the Taylor family. He and Karen quickly sleep together but the whole family is against him, especially Keegan's older brother Keanu who is furious that his mother would even go anywhere near Mitch. Keanu believes he is only in it because he wants something and warns Keegan off him. After a while, the family begin to except him. All apart from Keanu and his suspicions become correct when Ted Murray's PTSD is inflamed when he realizes that he will never be able to raise enough money to travel to Australia to patch things up with his son before it's too late. Ted's best friend Patrick Trueman wins a bet on the horse races, and posts it through the door which the Taylors share with the Murrays and when Mitch spots the money, he takes it and flees without even saying goodbye to Keegan or Karen.
In December 2018, he and Kandice Taylor turn up at Karen's house. Kandice sneaks him into the bathroom, and Karen walks in. She is furious, however Kandice eventually tells her that Mitch was just trying to fit a new bathroom.
