Drusus the Younger (d. AD 23)
Drusus the Younger, son of Tiberius, was consul together with his father (Dio 57. 20), and after the death of Germanicus Tiberius began to promote him as his successor (Fagan).

Drusus the Younger, son of Tiberius, was consul together with his father (Dio 57.20), and after the death of Germanicus Tiberius began to promote him as his successor (Fagan). According to Tacitus he could not stand Sejanus and once struck him in the face (Annals 4.3). His wife Livilla, Germanicus’s sister, according to Tacitus had an affair with the prefect.
Drusus died in AD 23. Tiberius went to the Senate while Drusus was still ill and presented Germanicus’s sons to the senators (Tacitus 4.8). Eight years later, after the fall of Sejanus, word spread that Drusus had been poisoned. Its source was a letter from Apicata, Sejanus’s former wife (Dio 58.11). Fagan considers this source suspect and the report impossible to verify.
