I've got a few possibilities here.
1) Mia failed his check ride, and the FI shot him down so he crawled inside a bottle somewhere, and shortly thereafter drove his pick-up into a bridge abuttment
2) Mia Failed his check ride, but his FI gave it up, so he's nose deep in Pooooo-haaaaa right now, not thinking of us for second.
3) Mia Passed his check ride, but his FI shot him down, and he's sitting in his car right now, sipping on some Cuervo, thinking about a creative way to off himself in such a manner that the FI feels guilty for the rest of her life.
My money is on 3.
