Also... perhaps some of you didn't notice but we got this today:
This is what I call a subversive affirmation, some of you might remember that term. It's an affirmation from a character corrupted by the premisse of a plot situation and a character's development. In the current situation, it's the overpowering power of Imu and the unseriousness of the crew.
Let me give you another info: The entire arc of Franky is - like Usopp - centered around pride. We are on an arc where the concept of pride is not only central thematically, but directly impacting the choices of the character. From Usopp this chapter the giants or Loki.
This is not a glitch that Oda decided to give Franky this line. This is a subtle warning. A sign of dangerous overconfidence.
The situation is about to go south.
