Boston Blue's St. Patrick's Day-themed episode puts Lena through the wringer after she finds a dead body - and is shot at. In Us Weekly's exclusive clip from the Friday, March 13, episode of the hit CBS show, Lena (Sonequa Martin-Green) arrives to meet someone named Connor, who is seemingly connected to a potential case. She can't find him and instead overhears shots being fired. Lena then proceeds to request a "patrol supervisor and some units" before she stumbles upon Connor's car.
