"There are always other options." He wasn't sure where he was going at this point however at least it was better than staying still. The boy's personality wasn't one he normally mingled with, and with all honesty it was starting to annoy him. However he wouldn't say that out loud, even if it was true. 

"Not everyone has the ability to dance, but everyone has the opportunity to learn. All it takes is a lot of practice, time and dedication. Ballet, of all forms of dancing, is one of the hardest things to master. You must look a certain way, carry yourself a certain way, and be rather flexible." He chuckled with a small shake of his head. "I am one of very few to master the ways of ballet. If you're lucky, I might teach you a thing or do. Perhaps not ballet.. But I know a few other types of dance that would be better for a duet."

"Well, I hope there are better options-"
The boy sighed, he didn't really think there was better for him. Being stuck in family business was troubling to him, he just wanted independency.

"And don't you sound like an interesting fella!"
He smiled, hearing Silas speak about his passion. Nico did find him fun, someone who has some mind to talk to someone as... Irritating as him. Did he act like this by purpose?
"I find dancing interes... Ting... Wait, duet dancing? Me and you?"

Nicola raised an eyebrow; dancing with someone? Now that's another new thing...

He paused in his steps - unsure of where else to go as he had no plan. He looked up and down the road before his eyes settled upon a tavern. A hot chocolate, his favorite drink, sounded good in this moment and so that's where he headed. All the while Nicola followed him. 

"Interesting." He corrected. Although it was a grammatical error and normally he'd be upset due to the boy having many imperfections, this time he found it sort-of charming in a way. He found that he was much more relaxed, it was odd. "Well, a duet is between two people, is it not?.. You said you would like to try and that it's something you have interest in. You stumble into a professional dancer and tell them this, I won't pass up the opportunity to share the thing I whole-heartedly adore."

The blue-haired boy slowly blinked, trying to understand the request of the taller one. It was surprising for him, a reality he never thought he would experience. Still besides Silas, Nico kept following him.

"I know, don't worry — I only, uhm... I was surprised, yeah-" 
Running his hands against one another, he began to fidget around, somewhat excited and nervous to the opportunity right before him. Dancing? With someone else? 
"Sounds... Pretty good! I just feel like I'll either fuck it up on first try or manage to go smoothly, hah-"
One of his hands rubbed the back of his own neck, alread buidling up possibilites of how that scenario could go.
