Deidra and Tyra are identical twins who have two things in common: Their breath-taking looks and strong hatred of each other. The word that best describes their relationship is 'malevolent.' Malevolent: wanting to do, or actually committing evil against another. Yet it can be broken in two, and form the words 'love' and 'lament.' For Tonya and Deidre, love isn't part of their equation. However, they do lament being born into the same family.
