Executive producer Rob Doherty revealed an upcoming season 2 arc for Lucy Liu's character, Joan Watson on CBS' Elementary.
Read the spoilers abound:
A skeleton will come tumbling out of the closet early into Season 2 when we meet “someone from [Joan's] past,” EP Rob Doherty tells TVLine. “We’ve alluded to a mistake she made when she was a surgeon that cost a patient his life. We’re going to meet someone, like a very real connection to that patient, and explore Joan’s feelings of guilt. At what point do you tap your guilt and give yourself permission to live a life?”
