Jace was in a trance. His usual of course whenever he throws himself at a task that requires a still mind. But even if he was focused on his task, his mind was open to other things such as voices coming from the other side of the room. He wasn't sure though if they had been standing and watching him for a long time?

Doing the final sweep, he pushed his way towards them, picked up the rag and greeted his friends. "Ohayo." he said giving each of them a grin as he placed the damp cloth on the lip of a bucket nearby.

"Are you here to practise? Good timing because I just had it cleaned." It was an honor to clean it for them because that showed respect for his friends. "Oh, come on in. Shoes are fine." he added as he saw the hesitation in Jasper's face. They were in Scotland after all. It'd be different if they were to enter their house in Japan, obviously.
