Im just watching episode 315 atm and i just noticed something that Helmeppo said:
(this is when they are talking about Dr Vegapunk)
"Strawhat, that devil's fruit you ate"
He's the one who identidied what powers it contained"
Ive noticed a lot of confusion from people as to how Shanks' crew knew that the fruit was the Gomu Gomu fruit.
Is it possible that Shanks stole the fruit from Dr Vegapunks lab?
