Biography
Paul and Carla fell out of love when Clyde was younger, and Paul ran off with her sister Melba. He came to live in Germany. Paul ran again, returning to Clyde's life, when Melba became pregnant. Clyde showed him the attic in Sarah Jane's home and explained to him that in his free time, he helped to save the world. Paul then stole a Berserker Pendant which made him go insane going on a rampage through the city before Sarah Jane, Clyde, and the gang made him take off the pendent returing him back to his normal self. Clyde told his father not to mess up his unborn child and that he should return to Germany and return all the things that he had wrongly acquired using the pendants power.
