Lucy returns to oversee the preparations for the Lassiters wedding expo and she fires Chloe Brennan (April Rose Pengilly) as the general manager of Lassiters, and reinstates Terese. When Mark Gottlieb returns to Erinsborough as well, the two spend time together and eventually rekindle their relationship. Lucy brings Mark in to assist with the wedding expo preparations, hiring him as a chef, and the two become closer. When Mark learns that Lucy needs to return to the United States for the opening of Lassiters in Las Vegas, he proposes to her and they have a ceremonial wedding on the first day of the expo, before leaving for New York, so Mark can meet Annie, before heading to Las Vegas, and then Paris for their honeymoon.
