Don't forget, we also know Rekieta is like super-rich, so rich that the dazzling glory of his wealth blinds us all with the myopia of poverty. So he certainly doesn't have the excuse of not having money to pay Randazza forever.
So if he chose to accept this dismissal, it MUST have been looking SUPER GRIM for him as to what might come out in discovery. Imagine! I think dosing his daughter with cocaine was practically NOTHING compared to what discovery would have revealed.
Imagine what a monster he must be!
