A gunshot and an awesome bathing suit are at the center of tonight's Nikita episode.

On "Dead Drop," the third-to-last episode of season two, Nikita and company will learn a troubling secret about Percy and Morgan Kendrick, the director of the CIA. What, exactly, is the link between these two?

They will also watch as Sean is shot by one of Percy's men, a development that has a profound effect on Alex. Watch the official trailer now and get refreshed on last week's installment via this review of "Shadow Walker."
