The executive assistant turned out to be a gold digger.
I remember from watching previous seasons, that Hurt’s wife was ill. From doing an online search I found that she had died in February of 2015. I didn’t care much for him when he was on the show. And although Todd is a dumbass (does he ever do any work?), didn’t Fred sneakily take Todd’s claim away from him?
