Exclusive: Michael Rapaport on Moretti's shocking return to The Mob Doctor

In Monday's episode, titled "Complications," Moretti kidnaps Grace with the help of her ex Franco (James Carpinello), who's been playing both sides in the rivalry between Moretti and Constantine (William Forsythe). Moretti binds Grace's hands and tosses her in a trunk, and we're guessing that unlike Constantine, it's not Grace's surgical skills he's after. So where is he taking her — and why? Viewers will have to tune in Monday to find out. But until then, check out this exclusive clip below:

The Mob Doctor airs Monday at 9/8c on Fox.
