I was overwhelmed by the amount of people, she says.

That was the perfect example of the scale of it.

To overcome any nerves, Ramsey channeled Lyannas tenacious spirit.

Im not that confident, really, but when I was her, I was, she says.

I love her defiance; shes a badass.

Being able to stand up there and shame all these grown men was super-cool.

Lucky,her veteran castmateswere also ready to lend a helping hand well those with their hands still intact.

Everyone was so welcoming and helpful, says Ramsey.

On set its like a whole new language: Theres all these crazy words that arent in everyday life.

Even the King in the North cant help but admire her.

He called me dude and told me they were cool!

And they say Jon Snow knows nothing.
