As they got closer to the palace and facing the court, Elsa felt her nerves getting the better of her. You had one chance to prove yourself worth keeping alive. Just one. She had one song. Her life hung on a single performance.
What song to chose for a life and death performance?

Elsa knew what she wanted to do, but also knew that it was important to tailor your work to your audience. She was trying to impress a being more powerful then she could imagine. The very spirit of Fall.

Hmm... the spirit of Fall...

A song hit her like a ton of bricks. It was perfect! Or at least she hoped it was.
One problem.
It was a duet.

She bit her lip. No other song would do. It had to be this one. But who could she convince to do it with her? She needed someone talented, someone who could play and sing with her.
Her eyes swept the lot of humans and settled on her only good option. The Native American woman, Vae.
Approaching her, she cleared her thought nervously. "I have an idea that could save us both from being someone's dinner or torture doll. But I need your help. You said you play the violin. Do you also sing? Do you know the song 'The Last Rose of Summer'? If we perform it together, perhaps we can impress the Fae King enough for him to keep us alive and unharmed. What do you think?"

It was the most Elsa had spoken to any of the people here after nearly a month of traveling together. Now that she was speaking about music some of her ice melted away. Her eyes now burned with an energy that only another musician could understand.
