How is it possible that a man with 4 wives (one of them who is a new addition) would be able to have 7 children when he is impotent?

Impossible right?

When the 4th wife was thought to be barren until a medical checkup, that was when all the "dirty secrets" in the family were let out. It can't be kept secret any longer...

Really interesting in different points of views of the characters. :D
