From Tardis Wiki, the free Doctor Who reference
Jonathan was the brother of Catrin and the son of Alan, all of whom had A positive blood. In 2006, when the Sycorax controlled the A positive blood in humans, threatening to make them jump from tall buildings, his mum tried to stop him. He was eventually released from the Sycorax' control. (TV: The Christmas Invasion)
