Felice caught the baton and nodded as he tossed it up with the others. "Ho bisogno di sapere se potrei lavorare con ti. E vorrei sapere la differerenzia." He took a moment to catch the batons again and hold them still. "Sincronizzazione. Calibrazione, anche." The slightly short boy tapped his head with one of the batons and motioned between himself and Roxy. "Penso che possiamo lavorare insieme." 

Putting his own batons away, the boy held out the rest for her to take before motioning back to himself. "Una dimonstrazione per ti, anche? Dimo...demonstration...?" 

("I want to know the difference." 
"Synchronization and calibration, also. I think we can work together."
"A demonstration for you, too?")
