Writing family drama is an exercise in contradictions. The most compelling relationships aren't fueled by hate—they're fueled by love that has curdled.
Infidelity introduces an outsider into the bloodstream of the family. The stepparent or the half-sibling is a living reminder of a betrayal. Complex relationships here involve children forced to choose loyalty to the wronged parent versus acceptance of the new reality.
These are often driven by jealousy, shifting preferential treatment by parents, or competition for a family "throne" or inheritance.
