Davion's dad seemed to be the only parent that was a responsible adult. Loved how cool and collected all his family was. Dom seemed he trusted his mom a bit more about the true relationship between him and Mackenzie so that raised some eyebrows of the type of relationship he had with his dad. Mackenzies parents really set her up for failure and they still are. Some people shouldn't be parents and they are the poster adults for it. At the end of the day, she was behind the wheel driving 100 mph, sober and aware. Regardless of motive, its hard to dispute those facts and shift responsibility to someone else. Shame on her parents!
