Elementary Exclusive: Gina Gershon cast as Joan's new nemesis

When Elementary returns, it's been nearly a year since Sherlock (Jonny Lee Miller) left for London and his new job at MI6. Suffice it to say, Joan is not too pleased with her former partner. Naturally, her new boyfriend Andrew is, in some respects, the anti-Sherlock, an oasis of normalcy in a life still rife with strangeness and drama.

Of course, Sherlock tries to get back in Joan's good graces when he returns to New York, so he'll tread lightly around Andrew in the beginning. But, let's be real, Sherlock can only ever mind his manners for so long.
