What Will didn't know, because he had been at work while it had been happening, was that he had been sparring with Arthur. Both Arthur and Tuck had been pretty lethal with the staves, and he had really enjoyed getting back into it.
So when Will swung at him, Tuck easily countered it, knocking Will's staff away, and Tuck grinned wolfishly at him.
Chances were, Will was going to win here in the end. He was faster and stronger. But it was all a bit of fun, really.
