Poisoned Pill

S2 E6: Alicia, Diane and Will must regroup when they're caught off-guard by a brilliant disabled attorney, Louis Canning (Michael J. Fox), who uses his condition to sway a jury during a test case for a huge class action suit against a pharmaceutical company. Meanwhile, Peter's campaign is at a loss as to what to do with rising star Wendy Scott-Carr, and Kalinda reaches out to a former friend, Donna Seabrook, to tell her to stop spilling her secrets to Blake.
