Me: "So, the Doctor's regenerating, but Clara's staying on."
My brother: "Huh, I don't think there's been a companion who's stayed on through a regeneration before. Except Sarah Jane."
Me: "Ben. Polly. Tegan. Adric. Nyssa. Peri. Mel. Rose."
My brother: "... Well, I haven't seen a lot of classic Doctor Who!"
Me: "Me neither."
