When two separate cases overlap (after a lead brings Bosco's team to one of Lisbon's crime scenes - nearly resulting in a shooting), Minelli orders Bosco's and Lisbon's units to team up for the investigation of a kidnapping crime; where the sister of a wealthy woman has been kidnapped, and work the case together. While the CBI attempts to find the culprits, the two different procedural approaches start to collide and soon cause tensions among the team members - Bosco struggles with the idea of working with Patrick and feels that he is ruining the reputations of those that he works with. While following a suspect, Van Pelt is shot and Rigsby shoots and kills the suspect after she attempted to shoot a member of Bosco's team. With the ransom deadline looming, Patrick realizes that there is an inside man, who turns out to be the nanny. The team finds her after she makes a phone call to the captors and traces the number to a house which they then arrive at to retrieve the woman. In response to his job well done, Bosco acknowledges that Patrick offers a valuable perspective and asks for his input on the Red John case.
