Dylan goes to Ciara's house and leaves her a voice message when she doesn't answer the door; unbeknownst to him, she is at a pub. Later, as she leaves, she collapses. The following day, at an AA meeting, Ciara is nowhere to be seen, which concerns Dylan. At the ED, David treats her after she is taken in, and doesn't inform Dylan of her presence. She soon finds him, and David tells him that he believes that she has been drinking. When Dylan asks her where she was the previous night, she becomes frustrated and leaves for The Hope & Anchor.
Later that day, her blood results show no traces of alcohol, prompting Dylan and David to go looking for her. They soon find her unresponsive in the pub and take her into the department. However, she soon discharges herself and leaves Dylan a farewell note. David tells him that it is for the best, but Dylan lashes out at him and publicly makes a comment about his bipolar disorder. He goes to Ciara's house to try to make amendments, but he is saddened when he is greeted by her husband Joel.
