The long story: Samantha can create an entity and give it its identity. She can decide how it looks, the emotions it feels, the way it carries itself and the actions it performs. She can also determine the series of events that it has to endure, be it joyous or unfortunate. She can give it life, and she can take that life away. In a sobering nutshell: she designs characters and their personalities, she is the storyboard, and also animates.
