Luffy twists the sword around, looking at it from every possible angle before he finally makes his decision.

"You're joking, right?"

The next sound that is heard is the sound of metal cracking, the sharp twang of steel being broken in half as the lad snaps the sword in two as if it were nothing more than a twig or a switch. Pieces of the blade crumble to the ground, falling and littering the floor on which they stand as a testament to many things.

It wasn't to prove a point of strength or conviction. Luffy knows all to well the character of the man standing before him. Despite knowing the ability for which Jack speaks of, there's more to be said here than trying to act big or overstep boundaries.

"Who the hell do you take me for? I'm not here to kill a friend."

A single foot brushes the debris out of his path, pushing along the remnants of the sword before a hand come up to clutch Jack by the collar of his shirt.

"Out of my way. You're not here to die a hero. You're here to live as one. Stand aside and let some one who's got a reputation for pissing people off take the fall, will ya'?"

It isn't said as a request, and it's quite obvious from his tone and eyes that the pirate is deadly serious in his proposal.
