Is the member of the family selling the journal. The journal belonged to the 1st mate on the black rock. Still curious as to how it got off island, and into the hands of the Hanso foundation.
I guess the DHARMA folks could've passed it along.
Or Ben is some double secret Hanso DHARMA OTHERS agent guy.
