Amanda is a friend of Chrissie Watts, first appearing in the show just before Chrissie and Den Watts are set to renew their wedding vows. She is aware of Den's nefarious behaviour and dubious associates, and sympathises with Chrissie over Den's affair with Zoe Slater. She plots with Chrissie to get revenge on Den, and looks into Den's financial affairs, finding a secret bank account Den has opened for Zoe, who is pregnant with his child. Chrissie is enraged, but Amanda convinces Chrissie to take a longer view so as to get as much out of Den as possible. She prepares legal papers to put Chrissie's name on the deed of The Queen Victoria public house, and Chrissie persuades Den to eventually sign (as a wedding renewal present) thereby making Chrissie co-owner of the pub. Amanda leaves after the vow-renewal ceremony, urging Chrissie not to go soft on Den.
A few months later, after Den's death, Chrissie is desperate to get full control of the pub (to sell it) and asks Amanda for help. Amanda returns to Walford, at which time Chrissie tells her that Den has run off with another woman and is in hiding again. Amanda wants to track him down, but Chrissie convinces her that it will take a long time to find him, and that she cannot stand to live in The Queen Victoria any longer, as Den's children Sharon Watts and Dennis Watts have returned. Amanda is aware of the way Den placed Sharon above all others (including Chrissie), and is resentful of her presence. Chrissie forges Den's signature on papers that give her full control of the pub, getting Amanda, after much hesitancy, to sign as a witness. Amanda then leaves Walford, taking the papers to lodge at court and Chrissie puts the pub up for sale.
