Drusus Julius Caesar
Apicata had bore Sejanus three children. He divorced her in the year 23 AD, when it seemed he might be able to marry his lover and co-conspirator Livilla, the wife of Drusus Julius Caesar (son of Tiberius). Drusus was a challenger to Sejanus's quest for power, but died in 23. Sejanus was reportedly seeking the imperial seat for himself and marriage to a member of the imperial family would have made his claim more plausible.
