Bob 'Mitch' Mitchell

First Appearance: Episode 482
Last Appearance: Episode 530

Key Storylines:
Bob 'Mitch' Mitchell meets Terry Hansen at the prison farm where Terry is jailed in 1984. Reaching the end of an eleven-year sentence for murdering a guy who was coming-on to his then girlfriend, Mitch is about to be released, and Terry asks Fiona to put him up as he has nowhere else to go. As soon as he meets Amanda Morrell, Mitch is attracted to her, and they end up sleeping together. Amanda falls pregnant, but Mitch is horrified when she tells everyone that it's the late Todd Fisher's kid; she was just using him. Mitch eventually forces her to admit the truth, but sadly she suffers a miscarriage, and the two of them agree to be just friends.

Mitch lands a job as the courier for Gordon Hamilton and Karen Fox's company, but he becomes frustrated at the fact that he doesn't earn enough money to do things that will impress Amanda so that she'll be interested in him. He's furious when Alan Brandon starts showing an interest in Amanda, so when Karen Fox asks him to steal some jewellery for her, he thinks about it, and although he's initially wary about being caught and going back to jail, he agrees to the idea because it's the only way he's going to get his hands on any decent money. However, Terry turns up halfway through the job and persuades him that what he's doing is stupid. To his fury, Mitch then discovers from Karen that the jewellery was fake anyway.

Still desperate to hold on to Amanda, Mitch effectively kidnaps her and forces her to drive to a shack in the middle of nowhere, which is owned by his former Sergeant in the army, Barney Adams. Amanda escapes a few days later by shooting Mitch with a gun he finds hidden under the couch. Mitch becomes increasingly unstable as he realises that he can't have Amanda, and as he then finds out that Barney wasn't the man he always looked up to (he discovers that Barney was partially responsible for the massacre of innocent women and children in Vietnam). He gets into a fight with Wayne Hamilton at the Fisher house, which results in him being knocked out. To his surprise, Karen Fox pays him to pretend to be dead and disappear - which he does, but not until he's sat in his car and watched Amanda for one final time.

A few months later, Mitch is surprised when Wayne turns up at his new home; Wayne forces him to admit the truth about Karen paying him.

Never wanting to give up her youth, she had a string of affairs while in her forties, but Barbara told her father about them, and when he died of - effectively - a broken heart, both children broke off their relationship with Dee. Stephen made up again about ten years later, though, and became a successful businessman - although he was always using Dee's money. At the age of 64, Dee returns to Australia from years overseas, and isn't happy about Stephen's new wife, Patricia. She drafts a new will, stipulating that Stephen and Patricia will only inherit if they produce a male heir. Patricia admits that she can't have any more children and so Dee comes up with an alternative plan: she asks her granddaughter, Amanda, to marry Wayne Hamilton, with money as the incentive to give her the grandson she so desperately wants. Before they wed, though, Dee dies. Her death leads to even greater repercussions after she uses her will to split her vast fortune between Wayne and Amanda, Beryl Palmer and Margaret Dunne, leaving Patricia and Stephen with nothing but a portrait of her.
