Kizaru tells the marine he's not really too concerned with the truth. Regardless of his heritage, there's one thing of certain of his value... he is a very powerful pirate!
Kizaru continues that he's just like Whitebeard when he was young. Only in his strength though.
Self-claimed Whitebeard Jr
Edward Weeble (former bounty 480 million)
Weeble seems to have the mind of an immature child.
"Dey always say da same thing! Dat ritebeard's sons are the ritebeard pirates! Mommy! Mommy! I'M the song of ritebeard rite? I'm so rite!(white)"
(I'm just localizing... he says "Shiroshige" instead of Shirohige because he talks like a little child and can't pronounce words right)
Miss Bakkin, self-claimed lover of Whitebeard replies to her son that Whitebeard pirates are nothing but pretend-family. The only true child of Whitebeard is you, my son.
She claims to be loved by Whitebeard, and shows her son Edward Newgate's picture. You couldn't possibly be anything other than his son, you look just like him!
She tells her son they need to find Marco and rest of whitebeard's men and rob them of Whitebeard's fortune. You are the true heir to his wealth!
But Weeble seems to be more interested in taking revenge on Blackbeard for killing who he believes to be his father. But Bakkin tells him there's no profit in revenge, money is what they should go after.
She reads a newspaper and learns about fall of Doflamingo, defeated by Garp's grandson.
She remembers a rumor that Marco and others protected him during the war.
Weeble says then he might know about Marco, should we go beat him up?
