[Prussia has come by the training grounds and is surprised to see them in use. He's even more surprised to see a kid swinging a sword about. He misses using weapons. He hasn't been able to practice a lot lately. In fact, the last time he held a sword was when they built the boat.

He watches a bit wishfully for a little while before noticing the second sword. It's not one that he's too familiar with, but with centuries of sword use under his belt, he's pretty sure that he could pick it up fast. A couple of practice swings to get the balance and then he decides to interrupt]

Oi! You! [he realizes he actually has no idea who the kid is] Whatever your name is! Spar with me!
