Guys, i've found out something important about the Doctor Who show. Some of the older viewers may know the Doctor only is allowed 13 different types of doctors. He is on his tenth. And so because of this writers remembered when the Doctor said he had a son. At the end of Series three (The one with Freema Agyeman as Martha Jones as the new companion) Writers will reveal the Doctor's Son! What will happen when he appears? You'll have to watch!
