REAL LIFE SOAP!
On As The World Turns, Daryl Crawford (Rex Smith) was unaware that he fathered Barbara's daughter, Jennifer Munson, until after the little girl was born.
In real life, according to The Calgary Sun:
(Rex Smith is) the long lost father of SHE co-owner Brandon Smith, of course. Brandon is a Calgary native that never knew that Rex was his father, and likewise, Rex was unaware of his first-born son.... When Brandon's mother became ill, she shared the news with her son that the man he grew up watching on Street Hawk was indeed his dad.
