River Song, excavator, professor, writer, adventurer and preeminent authority on pretty much anything you care to ask about and a bunch of things you probably don’t. As a person, she is pert, direct, often brusque, but her enthusiasm for life and her varied passions compensate for her sometimes highly opinionated nature.
She adds to this a sarcastic wit, and a delight in the absurd or in unusual situations. Over the course of her lifetime, River Song has been the Doctor’s assassin, his savior, his bane and his wife. She told him that he is loved and that he is feared. She is a woman who watched herself murder the man she loves, a woman who kept her eyes on a Weeping Angel after the loss of her parents because the Doctor couldn’t, a woman who knew a Silence was behind her and killed it sight unseen and without being able to remember what it was because her father looked scared. She finds particularly striking the idiosyncrasies of individuals or of events and her observations are often cutting and insightful.
She can be alternatingly abrasive, flirtatious, and self deprecating, and shows a keen insight and quick intellectual mind. River is brave, extremely clever, and very loyal – but only to a select few. Her allegiance lies where she chooses, because she hasn’t always had the choice. She abides strictly by her own moral standard rather than those imposed by society, a liar and a thief and sometimes a hero. She is a force of nature with her own gun. She doesn’t try to please anyone by being polite or appropriate.
