It seems that I am not at the top of my game and I apologize, a reader mentioned something that in part 3 he went to see her at night after her meeting, Osama saw her.
In part 4 I mentioned how he didn't know how she looked like, sorry.
I will make sure I am more careful.
I will repost it.
Also to clarify
Mesfer's sister is married to X, Osama is brother's with X, and Sultan is their uncle.
Is that a little clearer?
