Realising Charlie and Brax should be seen together, Heath tells the police that he hit Liam. Charlie then decides to leave the police force. Brax and Charlie decide to move to the city, accompanied by her daughter Ruby (Rebecca Breeds) and Casey. Peacocke stated "Brax is now with the one he loves. Charlie's left her job and her career for him, and he's left the brotherhood and the River Boys for her. They both realise what they had in Summer Bay is no longer there, so it's time for a fresh start somewhere completely new." However, Charlie is shot and critically injured by Jake Pirovic (Fletcher Humphrys). When they learn that there is nothing more the doctors can do for her, Ruby and Brax make the decision to turn off Charlie's ventilator. Anderson knew some fans would be disappointed that Brax and Charlie did not end up together, but the series producer had told her that after investing so much in the couple, killing Charlie off was the best option. On 13 February 2012, it was announced that Brax would take part in a cage fighting storyline. He decides to take part in the sport to raise some quick money to pay back Leah Patterson-Baker (Ada Nicodemou), who gave money to Geoffrey King (Geoff Morrell) on his behalf. Peacocke revealed that Brax is angry with Leah for paying his debt off and "coming to his rescue". Peacocke spent weeks rehearsing the choreography for the fight scenes with a stunt coordinator. "The Daily Telegraph's" Colin Vickery reported that the actor was often hurt during the training and he was left with cuts and grazes over his back. Vickery revealed that the cage fighting helped Brax with his grief over Charlie's death, while Peacocke told him "Every bloke has been through a tough time and you just want to punish yourself. There are plenty of blokes out there that can't deal with things emotionally and don't want to talk to anyone about it and they just want to put themselves in harm's way. Brax wants to feel some pain. For him, it is cathartic." Brax is knocked unconscious during a robbery at his restaurant, but decides to go ahead with a cage fight. Despite knowing he is not fit to fight, Brax "puts himself in danger by taking part in another tough battle". Leah tries to talk him out of it, but Brax ignores her pleas and goes ahead with the fight.
