Why did Donna have to bring so much luggage? None of the Doctor’s other companions have ever brought baggage; with the TARDIS’s wardrobe able to provide them with whatever clothing they might need, it had never been necessary. And if she had to bring all these cases, and shoe boxes, and hat boxes, shouldn’t she be the one carrying them all from her car into the console room? What did she think he was, a hotel porter?
“Oi! Be careful with that! I don’t want anything damaged, thank you very much.”
Donna was definitely unlike any companion he’d ever had!
