[to clara] stop it with the eyes. don't do that with the eyes. how do you do that anyway? it's like they inflate.

Out of all the companions the Doctor had by that point, Clara was the first who was in it for the wonder of traveling the universe. Although she did grow to love him, her first love was the prospect of seeing the stars and embracing everything that had ever come or ever would.

Clara will be missed by the Doctor, by Rigsy, maybe even by Ashildr and certainly by the many whose lives she touched. But Clara Oswald, the funny, feisty, heroic and human Impossible Girl, will be missed most keenly by us.
