Has anyone else considered that thru all of Williams medical testing we may find out that William is not really Randall's bio dad after all? Maybe William will need blood and when Randall goes to donate...... Oops! Nope he's not your dad!! William of course thinks he is Randall's father but Randall's mom was a drug addict and another man may be Randall's bio father.
I hope they don't do that LOL! I don't think they would go that route, not after all the back story with him and Rebecca's meeting when Randall was a child etc.
