Chris and Billie really did a magnificent job with this scene. Just look at the facial expressions! He absolutely embodied the fear that The Doctor had for Rose's safety, and she completely nailed the fierce nature of the Bad Wolf.
This is so true! My father and I wanted to watch the season of The Walking Dead, but we hadn't finished the last 4 seasons. So we decided to watch all of them in 3 days, Then 1 episode a week, it felt like forever.
