I actually do not believe that TJ is thinking “scam”, since this seems like a genuine opportunity that would benefit both of them. Tiffany would no longer be alone in the mansion, and TJ would have a (presumably) world-class kitchen where he could indulge his culinary talents.
This is going to blow up in Tiffany’s face in one way or the other. Either her father is going to be really upset the Tiff ruined Ann’s surprise, or there’s more to this picture than the obvious and she may have set the wrong wheels in motion.
Actually, it’s “remuneration”.
