This episode's medical case was an interesting (different) take on the addiction to Opioids issue that we are constantly (and irritatingly) hearing so much about. (It's a pet-peeve of mine that because 'some people' are predisposed to addiction and dying of overdoses, the rest of the world might suffer needlessly should they decide to pull these much needed painkillers off the market. Why the hell can't they figure out a blood test that will help determine if a patient carries whatever 'marker' predetermines they will become addicted to these things so that others don't have to suffer????) Anyway.... it's a slightly different take and fascinating if it is a 'real world' possibility.
But what made this episode great for me was where they took the story regarding Dr. Murphy's personal relationships. I really want to give spoilers, but I won't--if you are a fan of the good doctor, this isn't an episode you'll want to miss regarding the story arc with Shaun and his women.
