"In the chapter you see white lightning when Law uses Haki on him (Doc Q), but not the black lightning we've seen before when someone has used Haki with "Conqueror Haki"."
We know that Law doenst use conqueror haki, repetitive info....
Anyway, Law didnt lose, so this fight is still open, maybe someone will jump and help law in this fight, who knows, Urouge maybe drop from the sky to balance the fight
