Archie Moses is a small-time thief in Los Angeles who smuggles drugs for drug lord Frank Colton, who launders his drug money through a car dealership. Moses is unaware that his best friend, Rock Keats, is actually LAPD undercover cop Jack Carter, who befriended him only to infiltrate Colton's gang. Carter has Moses include him in Colton's next drug shipment, secretly planning to arrest Colton and take in Moses, whom he has come to care about, unharmed. Carter's undercover status is revealed before he can enact his plan, however, and a hurt Moses pulls a gun on him. During the raid on Colton's warehouse, an out of control crane hits Moses in the back, causing him to accidentally shoot Carter in the head. Moses then flees the state, and is subsequently found and arrested.   Carter miraculously survives and makes a full recovery with the aid of his physical therapist, Dr. Traci Flynn, with whom he falls in love. Moses is brought into custody, and he agrees to testify against Colton, but the trial is set to take place at the other side of the country. Carter's superior officer, Capt. Jensen, orders him to personally transfer Moses to the courtroom. Carter harbors resentment against Moses, and tensions escalate once the simple transfer goes awry. Colton learns through bribed federal agents and LAPD officers of Moses' attempt to testify against him. As they flee from Colton's men, Carter and Moses slowly mend their friendship, and are successful in returning to Carter's precinct. However, Colton apparently holds Flynn hostage, and blackmails Carter into turning Moses over in order to save Flynn.
What is the last name of the person that the undercover cop has come to care about?

I work as a painter for a living. Sometimes people want wallpaper which I do not like, but the customer is always right. First I put a coat of primer on the wall so the paper will apply nice and smooth. Then I have to cut and measure the paper. I have a special machine that lets me roll the paper out to the length I need and then cuts it in straight lines. Then I have to put glue on the paper. I apply it to the back of the paper then stick it on the wall as evenly as I can. I use a paint knife to smooth out any bubbles in the paper. Then I wipe off any excess glue with a wet sponge. Now it's time for the next piece. I repeat the process and make sure the pattern lines up. I repeat until all done.

Why are they repapering?
