Brothers and sisters don't always get along, but on the new episode of "Mob Doctor" (Fox, Mondays at 9:00 p.m.; episodes also available on iTunes, Hulu and Fox on Demand for free), we see one pair who have slightly weightier problems than who ate the last Pop-Tart.

Dr. Grace Devlin (Jordana Spiro) is a promising surgeon who finds herself pulling bullets out of mobsters to pay off the dangerous debt of her brother Nate (Jesse Lee Soffer). In this clip, Grace puts Nate squarely in his place -- and we're pretty sure he won't be popping by her work to vent his spleen (unless he literally needs to vent his spleen -- she is a doctor, after all) for a while.

In the rest of the episode, mob kingpin Constantine Alexander (William Forsythe) calls on Grace to treat the fugitive mobster he’s expecting to partner with in a shady video poker deal. And at Grace's "day job," she and Brett (Zach Gilford) treat a bride who’s bolted for the emergency room in the middle of her wedding. Let's hope she brought everybody some cake.
