When Season 3 kicks off on Oct. 30 (CBS, 10/9c), “Things don’t get off to a great start” between the two women, executive Rob Doherty tells TVLine. “In fact, their first confrontation is physical.”

Elsewhere in the extended promo, tensions appear to be at an all-time high between Joan and Sherlock following his return to New York; guest star Gina Gershon has a death wish for one of the main characters; and Watson appears to be peeping in her former mentor’s home.
