I heard about this quite a while ago ... Ziad made genetic studies for himself and his son and discovered from the DNA analysis that Assi isn't his son !!!! ...
I guess one day he saw him in the kitchen and took a good look to his head and found it's similar to "
صهريج" so he decided to run the test
...
Even in the silliest details his plays turn to be true (what an irony !!!)
Thank You ...
