In "The Man Behind the Curtain" in Ben's flashbacks, he finds himself first meeting Richard. When he mentions how he saw his mother, who died off the island, Richard is stunned. I always just assumed that he was recognizing young Ben's communion with the island, but now I think it relates to something much different. I think that Richard immediately thought of Isabella, who also died off the island, but later appeared to Richard. I dunno. Just a random thought.
