Tiberius sent Gnaeus Calpurnius Piso to assist her husband, naming him governor of Syria. During their time there, Germanicus was active in his administration of the eastern regions. Piso did not get along well with Germanicus and their relationship only got worse. In AD 19, Germanicus ordered Piso to leave the province, which Piso began to do. On his way back to Rome, Piso stopped at the island of Kos off the coast of Syria. Around that time Germanicus fell ill and he died on 10 October AD 19 at Antioch. Rumours spread of Piso poisoning her husband on the emperor's orders.
