adpQ1bn5Hkw&feature=related
versus
The Ninja Clan ("The Last Samurai"π
The Ninja clan have killed Katsumoto and have moved into the Samurai village. The Ninja are in full gear, they know an attack is coming, but they have no idea when and what form it will take, and they have limited knowledge of the Hassansins.
Scenario two: The Hassansins are in place of the Ninja. They must attack the Samurai village and kill Katsumoto. Do they clear? Remember, the Samurai have no idea of the pending attack, just as in the Ninja attack.
