Note: This Question does not contain much of a spoiler, as it is from S1E1, but answers might, so please declare if so.
In The Spy, in one of the early scenes, the protagonist is shown in a prison cell, apparently tortured on both hands, writing a letter.
He does so, from left to right, with his left hand.
Since he is of Arab heritage, and a Jew, I expected him to write from right to left in any case.
I do not believe this is a mishap, is there an explanation for him writing left to right (either in or out of universe)?
