Elsa started when a voice spoke to her and paused in her playing. She got so involved in music she sometimes forgot her surroundings. 
It was a young man who she remembered from the group. She resumed playing after a moment. 
He had said something. She should reply, right? But what to reply? What was there to say? Elsa was terrible at making small talk.

"It is my favorite piece by Yiruma," she said. "You might know who that is. He has become more mainstream since the Twilight movie franchise basically plagerized his work for their films," she froze for a second and looked at him with wide eyes. "I apologize if you enjoy that film series."

After a bit she tried again. "It's called Kiss the Rain. Yiruma is one of my favorite composers. You... you are an artist, correct?"
This was possibly the most she had said to anyone and definitely was the most amiable she had been. Music had the ability to change her into almost a completely different person. Elsa seemed more at peace, more open than she had until now.

"Are you nervous at all? I am. I just want to survive. I am praying one of those creatures sees some use in my musical abilities and will keep me alive for entertainment purposes if anything."
