While visiting his great-grandmother at Erinsborough Hospital, David befriends Paige Smith (Olympia Valance), who tells him about Angelina Jackson (Sarah Howett), a patient who has a brain tumour. When Karl Kennedy (Alan Fletcher) comes to check on Paige, David introduces himself and reveals that he is a first-year resident at a hospital in Sydney. He offers to contact renowned neurosurgeon Dr. Anward Adisa (Yasmin Bushby) about Angelina, earning Paige's gratitude. While talking to Karl about his residency, David memorises Karl's hospital system password. Aaron Brennan (Matt Wilson) asks David and Leo about volunteering for the Blaze Outreach program and David drops off a first aid kit to Amy Williams (Zoe Cramond). She later catches him logging onto a computer using Karl's details. He admits to her and Karl that he is looking for his father, and Karl later finds information about a man named Bradley, who was banned from seeing David and Leo's mother in the hospital. Aaron sets David and Amy up on a date.
