I’d like to take a moment to talk about Clara and her need to be in control. This seems like a funny, throwaway line but it’s not. Instead it highlights a trait of hers that permeates every aspect of her life. This need to feel in control effects everything that she does. She chooses jobs that place her in the position of power, that allow her to run things as she likes. She spends years thinking about travelling but not doing it because that would require stepping into an unfamiliar environment, somewhere she has less knowledge and less control. I often wonder if she always had this desire to control what she’s doing, when she’s doing it, and who she’s doing it with, or if it devloped later, after her mother died for example. We see this trait show itself in her refusal to stand back and let whatever happens to Merry happen, the ease with which she steps into the role of commander in Nightmare in Silver, the unseen conversation she has with the Doctor on the submarine that leads to her stepping into a room alone with an Ice Warrior. She’s positively frantic at Christmas as everything spirals out of control - nothing is cooking properly, her family are going to ask her uncomfortable questions. Control = adulthood, responsibility, proving herself to others. Clara’s control is one her biggest flaws and her greatest strengths.
