Now, for the last act ...
Hutchins obviously excells at what he does and that is something the goverments (both of them, UK and US) will not want to lose the opportunity to take advantage of, especially if with his work he has discovered a few things he should have not.
Just where do you think the tip-off to the FBI came from? He traveled to Las Vegas of his own free will and thus it was easier than accepting to extradite him (a UK citizen) to the US, no real political price to pay.
First Act: hold him over a fire till he admits culpability and shows regret (done)
Second Act: throw the book (and then some) at him (in progress)
Third Act: make him an offer he can't refuse: no jail time, a slap in the wrist and a nice long contract working for the BigFive.
With no exit clause, naturally.
