I like this new arc for Chris. It not only makes perfect sense and plays right into the show’s history, it is also is very consistent with Chris' personality. I know that a lot of the commentary on this last week’s plot was that Chris was being stupid and he was. He had no business accepting the deal with Paul after Lucas told him not to and he definitely should not be getting behind the wheel of the car with no license.
But it’s been long established that Chris is the type of person who needs to feel needed, is practically obsessed about fixing a problem and he has no issue with lying if it suits him. Plus, given that he feels that the problem was his fault to begin with, I can easily see Chris going to great lengths to resolve it.
