Martin's scheme will be the thing to push Casey over the ledge. He will be forced to confide in Shawn to get help against Martin. Otherwise, I think he wouldn't tell Shawn for a very long time. Will something happen in that cove at the full moon?
By the way, I don't think you get the Nobel prize the same year you release a discovery. Most who win do it for work published 10-20 years before. Not saying Martin wouldn't be able to hope for a prize, but not in the immediate future. But artistic freedom is great, so you can tweak reality to suit you. As a Swede, I just reacted to that.
