She tracks down the culprit - Carbo who reveals he thinks of toothbrushes as common property.

But when Nathan receives separation papers, will Melissa and Ben risk hurting him further by telling him the truth?

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.
