I think that grayson can claim over 50% of nolcorp but i am not sure if it is gone completely. I think it just means nolan will no longer have majority share. To answer your other question, emily told mason that if he does what she says he can write the book of his lifetime because once her vengeance is complete she will give him all he needs. Basically playing to his ego. It was a good scene!
