Jason is the second oldest Walton boy (he is only two years younger than John-Boy but seems to be continually trying to catch up with him). He sometimes feels that John-Boy is perfect and that he needs to raise the bar. Though John-Boy and Jason often fight, they share a very close brother/friend relationship. Especially after John-Boy went away to college, the two became very close. Jason has a great relationship with his other brothers too. Jason and Ben often take their girlfriends and go on double dates. Jason gives great advice to Jim Bob and encourages him to reach his full potential. And of course, Jason loves his sisters a lot as well. He also finds it difficult when his father expects him to join him at working in the mill when he finishes high school.
Jason is musically inclined, and decides to study music seriously. He earns a scholarship to study at the Klineberg Conservatory. At times he plays as a part of a group, both singing gospel music on the radio, and also playing at dances.
He eventually takes over the Dew Drop Inn and marries Toni, a woman he met whilst in the army. They have 5 children, all named after different country/western singers of that time.
Jason's personality is very easygoing, patient, kind, and calm, even in a crisis. He is friendly and outgoing. He is friends with many people and has few enemies.
