‘Why not?’ you say

The man looks confused.

‘My name is Leopold Dessrict, the finest sword fighter in all Christendom’ he says as he waves his sword in a  discerning but ostentatious way.

‘You may not pass…….  because…..   errrr…..  it is my destiny to fight you’

He doesn’t look completely convinced

Do you

Wave your sword in a wearisome and filthy way and prepare to fight him

Say ‘Whatever’ and shoot him.

Say ‘Are you sure?’
