Ted struggles with feeling old and worthless after a girl gang attack and the death of a neighbour. Returning from a movie, Ted and Chel become involved in a teenage girl gang's vendetta. In the melee, Chel falls heavily and Ted rushes her to hospital. Kidney damage has occurred and Chel's dialysis is upped to three times a week. Ashamed he couldn't protect Chel, and feeling marginalised by the world, Ted begins to retreat into himself. Melissa discovers someone has been using her toothbrush. Already feeling marginalised in the house full of men and lacking in privacy, this is the last straw. She tracks down the culprit - Carbo who reveals he thinks of toothbrushes as common property. Nathan's sympathy and gift of a new toothbrush only makes Melissa feel worse about keeping Sammy's secret. But when Nathan receives separation papers, will Melissa and Ben risk hurting him further by telling him the truth? Dave raises the spectre of kidney donation. With Julie's tentative blessing, he lays it on the line with Chel. To his surprise, she accepts his offer to test for compatibility - she wants to see baby Ruby grow up. Meanwhile, Ted and Julie become concerned at the quiet absence of neighbour Mrs Luscombe. A simple visit turns to horror as they discover Mrs Luscombe has died. To Ted, this is another example of the world marginalising the elderly - and he resolves to make a difference through a seniors self defence class and a phone tree, reclaiming his sense of self. Carbo's internet fame jumps to a new level when he begins receiving sexy gifts from a secret admirer.
