Thanks for nothin', kid. (spoilers)
Life is good for our mechanic. Getting the job done and moving on to the next job. Then Mr. Hot-head Steve shows up. He's got to stop Steve from getting sloppy with the carjacker, the kid doesn't follow directions killing the hitman, and on another job, a dropped piece of hardware causes them to have to leave a building the hard way with guns-a-blazin'. Our mechanic also has to avoid Steve's hit on him and he gets his house and prized Jag destroyed.
He's trying to teach the boy a skill, but gets crapped on at every turn by this punk.
