Don't forget there's a familial attachment with Nichole being his daughter. That said, there's no ethical reason to renegotiate their contract. Neither party anticipated their "adventures" with Seamus depending on secrecy to accomplish his goals.
Ethical reason or no, this is a big opportunity. And I didn't say "blackmail" or "break contract". Or even "renegotiate". I said "negotiate", as in negotiate for opportunity to buy into the project, ask about possibility of getting part of the salary as percentage, etc.
Think Apple. Think Steve Wozniak. And think what happened to Ronald Wayne. https://en.wikipedia.org/wiki/Ronald_Wayne
Even minimal contact with the project and attending fallout will give an intelligent person plenty of opportunity to get very rich. The trick will be to stay ahead of the mega-corps attempting to find out and seize control of the project.
Quite. Which is, if I was Seamus, reason I would want to harness and channel Nicole's self-interest. Last thing he wants is Nicole staying nights awake, thinking up technically-legal-but-damaging-to-enterprise ways to cash in.

You're quite correct that the important thing is keep ahead of OmegaTek and GenSaxWal. If they realize what Seamus is after, they will do anything (and I mean anything
, including acts of war or genocide) to capture Seamus.
As depicted Seamus doesn't seem to be the type to stiff his help, without whom, the project would fail.
Indeed. Still, as Ronnie Raygun put it, "trust, but verify".
