Once Barnabas appeared, they seemed to completely forget the original premise, which was Vicki's wish to learn her parentage, and hoping she would find it in Collinsport. She had already unearthed a few clues, one of them being the picture of Betty that Sam Evans gave her, and which Carolyn said, upon seeing it, "When did you have your portrait done?" Only Liz and Roger denied the resemblance to Vicki, for obvious reasons.
Too bad we never learned who Vicki's parents were. It would have been a nice denouement to the denousement of her storyline.
Love, Robin
