Jango is surprised, and Usopp is shocked to hear they found 5 million Beli on their ship, wondering, "5 million? Why would those guys have so much money..." Desperate, Usopp yells out, "That is my treasure! But! I can give it to you!!

Usopp points and bargains, saying, "I will give you the treasure, but you must retreat!!" The pirates are excited at first, but Jango calls Usopp an idiot. Jango declares, "Of course we're going to take the treasure! But, we don't have to retreat!" Usopp is horrified by Jango's ruthless logic, thinking, "That sly bastard!

This isn't the time to let us pass!" while others wonder, "Who the heck is that girl?
