After his release, Reginald married Helvis, the eldest daughter of Balian of Ibelin and Maria Comnena. He then played an influential role in the politics of the Third Crusade. He supported the annulment of the marriage of Humphrey IV of Toron and Isabella of Jerusalem, so that Isabella could be married off to Conrad of Montferrat; the anonymous author of the "Itinerarium Peregrinorum et Gesta Regis Ricardi" calls Reginald a member of a "council of consummate iniquity" (together with Balian of Ibelin and Maria Comnena and Payen of Haifa) for supporting this act. His Arabic skills made him useful as a diplomat: he negotiated with Saladin on behalf of Conrad in 1191-92, and later helped negotiate peace between Richard and Saladin in 1192. Sidon was recovered from Saladin in 1197.
