Jaimie has never much liked Taub but agreed to help him out so he could make support payments to his sister. He offered Taub a job as a non-testifying medical expert for about $50,000 a year for 15 hours of work a week. Taub was somewhat desperate and accepted.
However, Taub saw an x-ray of one of the opposing plaintiffs, Timothy a boy who was injured in a very bad traffic accident. Taub becomes convinced the x-ray shows a dangerous injury and eventually seeks out the boy's mother Kara and convinces her to take Timothy to the hospital.
The anomaly was a harmless irregularity in the skull, but Kara was mad that Jaimie hadn't told her about it and withdrew from a settlement agreement. Jaimie was enraged by the settlement falling apart and tracked Taub to the hospital where he punched him and told him to stay away from Rachel.
