Gaetulicus was very secure in his post in Germania Superior: he was popular with his troops for his kindness and moderate discipline, while his father-in-law Apronius governed the adjacent province of Germania Inferior. Tacitus further mentions a rumor that Gaetulicus and the emperor Tiberius had come to an understanding: the governor had sent him a letter reminding the emperor that he had aligned himself with Sejanus at the emperor's advice, not his own choice, had no part in the affair that led to Sejanus' destruction, and would remain loyal as long as he was left undisturbed in Germania Superior.
