Lang is placed within a small terrorist group called the Sword of Justice as a Minnesotan named Ricky, officially to gather intelligence and minimize casualties. A Dutch politician is seemingly shot dead by Lang in Switzerland as a warm up activity by the Sword of Justice, although it was a set-up and the politician was briefed and was wearing body armour. During a brief return to London Lang encounters Sarah and confronts her regarding pictures, provided to him by his friend and handler Solomon, showing Sarah and Barnes together. Sarah admits to being a part of the conspiracy, but swears her father's death was never part of the arrangement.
