Betrayals

In this event, he/she gets betrayed by a family member or someone close to them who reveals himself/herself as the villain. But betrayals have a Heroic side - In some situations, some villain betrays other villain and takes hero/heroine side in the unexpected moment. In some other cases a pawn of the main villain betrays their master and joins the heroic side instead.
