Knight vs Pirate...boy, they sure blew this one. After demonstrating that a flintlock pistol can't penetrate a steel breastplate and that a grenado is little more than a flashbang to an armoured knight, they still gave the win to the pirate. The only weapon shown to penetrate armour in the pirate's arsenal was the blunderbuss and only at ranges of a few yards. Assuming the knight hadn't already killed the pirate with a crossbow by then, he would be close to melee range by the time the blunderbuss becomes effective. That one shot won't likely kill, but the knight's counter with morningstar or broadsword certainly will. The pirate is dead every time.
