Why does the protagonist write from left to right?

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)?

Best Answer

It's revealed at the end of episode S1:E6.

The reason is, it's written in French. It remains a mystery to me why he chose French, but it seems it does not matter to the plot at all.
