Extremely mild spoiler warning:
For some reason, I love these villains. They're beyond creepy, especially in the latest episode! *shudder*
Anyway, this is 11th Doctor, Amy Pond and River Song running away from the weeping Angel. Just in case you couldn't tell.
Why is the angel going "Nom Nom"? Because I felt like it, that's why.
Doctor: "Don't panic, Don't panic, DON'T PANIC!"
Amy: "What are we doing?! I can't seeee! Will somebody explain?!"
River: "WE WERE SAFER IN THE GAOL!!!"
