I want to know the answer to the following question:
Did he think he would be gone a long time?
All the background I'm provided with is that "In the meanwhile, Julian, who seems to have become suddenly jealous of the influence that Athanasius was exercising at Alexandria, addressed an order to Ecdicius, the Prefect of Egypt, peremptorily commanding the expulsion of the restored primate, on the ground that he had never been included in the imperial act of clemency.". Is that enough to answer the question?
Answer: no
