A parent step in? You mean Barb, the hoarding, angry, manipulative woman who, along with Bob, shielded Chris from any consequences for his shitty behavior and, in fact, enabled him by letting him use his very, very mild form of autism as an excuse to extricate himself from any responsibility in his life? One half of the shitty parent duo that turned Chris into who he is today? You want that parent to step in? He or she is 33 now. It's time to cut that umbilical cord. Well meaning people have been trying to get Chris to make the right decisions for most of his life - to save, to focus on school, to leave Megan alone, to not spend so much money on Legos and Sonic crap. He never listened to them. He's not going to listen to them over taking hormones.
