Dabbling In Fringe Science
Now that makes a lot of sense. September has told Walter that he could tell him all the different futures but he could not tell him which would come to pass, but he also said he could not have predicted that Peter would catch a firefly that would ultimately lead to the death of Bobby. I believe his appearing to warn Oliva was an attempt to help save her, a hope that intervention on the human scale would set forth a new possible future, that they could not have predicted.
