Nolan asks Grace to come over to his newly renovated kitchen for dinner and she accepts.
Nolan’s estranged father died and left him $14.00 and his 1971 Chevelle. He hasn’t seen his father in over 30 years. His half-brother, Pete, drives the car up from Tempe and brings it to the station. Nolan, not knowing Pete is his brother, says his father was a piece of crap. Pete punches Nolan and Harper arrests him. Nolan lets Pete go but when Nolan asks if Pete wants to get together he storms off, but comes back to apologize.
Just as Nolan and Grace are about to kiss at his house, they hear the Chevelle being stolen. They track down Pete and he and Nolan talk. Turns out their father loved Pete but wasn’t always so great. He drank a lot, gave Pete his first drink at 13 and his first joint at 15, so maybe Nolan dodged a bullet. Pete gives him back the car and gives him half their father’s ashes. They promise to keep in touch. Before Grace leaves for the night, she and Nolan finally kiss.

Tucker got the ticket from Cole, who committed the robbery and murder. When Cole tries to cash in a ticket at the train station, Harper and Nolan try to arrest him but he runs and holds a gun on a baby. They convince him to give himself up before anyone gets hurt.
Pete comes back and steals Nolan’s car again. This time Nolan lets him take it.
