Dina Goth (nee Caliente, and formerly Bachelor) is the younger daughter of Flamenco and Nighat Caliente, the twin sister of Nina Caliente, the widow of both Michael Bachelor and Mortimer Goth, the stepmother of Cassandra and Alexander Goth, and the mother of Francesca Goth. She is also the ex-girlfriend of Don Lothario, and the aunt of Nino Caliente.
Dina had always wanted a rich husband, and she got one in her first husband Michael. However, Michael died soon after the wedding, leaving Dina a widow. She spent the money he left her quite quickly, so she needed to find herself another rich man.
That is when she met Mortimer, a lonely old man who had lost his wife mysteriously. Dina befriended Mortimer, who was grateful for the company. Dina made her move, and the two were soon engaged and then married. Dina expected her second marriage to go quite like the first - Mortimer was getting very old - but she fell pregnant unexpectedly. Later her daughter Francesca was born, and not long after, Mortimer passed away of old age while Dina was at work.
Dina would have left to find another rich man, but now she has her daughter and teenage stepson to take care of. Alexander hates her with a passion, but he does love his little half-sister and helps to take care of her.
