Ok so in Ch.700 it's revealed that this guy called Absa is leaking info on pirates. So with what seems to be the escape ship from Thriller Bark appearing in the page Kid appears I'm inclined to think that the info leaker is Absalom. His DF would only help if he is the info leaker. The name fits, plus the arrival of that escape ship from Thriller Bark, which he was on. Seems to add up IMO.
