Omar didn’t remember how he got there. There was no apparent reason why he wouldn’t. He wasn’t hit on his head. He was not drugged. There is no efficient correlation between lack of oxygen and immediate loss of memory. If he had walked from Beirut to Cairo, it would have been tiring, but can one be too tired to remember? That would be interesting. Omar had walked from Beirut to Cairo in an underpass under the coast of Palestine. It was a trip that not many make. It still is, as the underpass must remain secret.
