Madison's relationship with Jason was strained; she called Jason by his first name, not as "Dad," even though he legally adopted her the previous year. Jason thought she was a pathological liar and "carried on like a moron". She told Jo that she knew Jason did not love her like he did the boys, and did not feel that he acted like a dad (so she would not call him Dad). Jo helped the two of them mend their relationship. Jason extremely hated her.
He did not trust her to be responsible and said she often lied about whether she completed chores or homework in order to get out and do what she wanted, like horseback riding or shopping. Jo introduced Trust Bucks so Madison would be aware of her responsibilities and earn privileges.
She was 13 when she appeared on Supernanny and is now 23 in 2018.
