MARTHA JONES. OH MAN. Okay, I love how she's so goddamn smart and competent that she just keeps getting it right in a way that just makes sense, because it's her. I love how she loves the Doctor but still challenges him. I love how she saves the fucking world, okay, and she does it by telling stories. I love how she's more badass than anyone but still feels like such a completely real person. I LOVE HER. SHE IS MY FAVORITE.
