Jam is a boy two years older than Kaladin. Jam's father was a soldier in Amaram's army. Kaladin's father, Lirin, noted that Jam's father had a lame leg which upon which he'd had to operate three times; a 'gift' from the war. Kaladin watched Jam train with the spear despite that Jam's father had been injured (or, perhaps because he had been).
