Insult to Injury

A young woman whose parents were killed by a drunk driver in 2009 (while she was in the back seat) calls the precinct after seeing that the perpetrator is out of prison and back drinking in his favorite bar. She vows to kill the man and then kill herself, and Danny has to do all he can to keep her on the phone and delay her actions until they can locate her. Jamie gets a phone number from an attractive courier while on patrol with Eddie, but later finds the young woman gave him a fake number and is working for a counterfeiter. Rather than arrest her, he does the job of a detective and has her lead him to her boss, before reconsidering and turning the case over to the proper people. Elsewhere, Frank has to replace Linda as a chaperone for Sean's class field trip to a museum, and he tries to convince the head chaperone (Annie Wersching) to be less rigid.
