Karina is support worker at the psychiatric hospital (Hummingbird Mother and Baby Unit) where Stacey Branning is staying with her son Arthur Brian Fowler after suffering with postpartum psychosis. Karina attends a meeting with her colleagues Dr Patricia Reid, Nurse Anya Barowski and Nurse Madhu Singh who recommend that Stacey is discharged, and Karina tells Stacey she will support her as she adjusts to life back at home.
She then later visits Stacey at home to check she has enough support from family members.
