O'Neill before the bombing targeted towards SAMCRO
Jimmy has O'Neill tell Jax over the phone that Abel is not in Belfast. When SAMCRO tags along with SAMBEL on a protection run for a gun shipment, O'Neill leads them into an ambush by the state police, but SAMCRO overpowers the police. SAMCRO then interrogates the officer, finding out that they have been paid to detain them by an unknown employer, most likely O'Phelan. O'Neill's back-up plan is to secretly bomb a gun shipment that SAMCRO is protecting. While he is able to detonate the bomb without raising any suspicion, the plan ultimately fails as all SAMCRO members survive without any serious injuries. Knowing he is the prime suspect in the bombing, O'Neill goes on the run. He is ultimately captured by SAMCRO, brutally tortured by Sean Casey for information about Jimmy O'Phelan, and eventually shot to death by Jax for his betrayal to the club.
