The captain points toward Zoro and commands, "BUCHI, SHAM... WE COULDN'T PASS THROUGH THIS SLOPE......BECAUSE THOSE GUYS ARE BLOCKING OUR WAY! NOW GO AND DESTROY THEM!"

Sham panics, "EH!? WHY MEEE!?", but under the captain's intense glare, he reluctantly steps forward, crying, "OKAY! I'M GOING! GO!". Nami watches in disbelief, wondering, "WHAT'S GOING ON?
