[Holds a hand over his eyes trying to figure this out. The words are there but they're tangled up in so many things. No, Marco isn't going to go kill anyone yet, if anything, he's just confused. What does this have to do with blood at all? Of course it's a sensitive topic for Ace, and Marco is... extremely overprotective to understate it vastly. However, he can't understand the trains of thought.]

He thinks you have a thing against Luffy's blood? Did you tell him you're brothers? Or that you have the same crazy ass Grandfather who punched you and nearly broke your best friend's jaw? [Yes, he just titled himself Ace's best friend, deal with it. Also he's way too exaggerating Garp's punch since nothing could break Marco's bones, but whatever.]

Here. [Holds out a hand for Ace's journal.] Let me see. [Holds up a hand.] I won't kill him if you insist. I just don't get how the conversation went from Luffy to something stupid.
