Alan (The Christmas Invasion)

Alan was a man who lived with his wife and children, Catrin and Jonathan. Like his children, Alan had A-positive blood, so when the Sycorax used blood control on A-positives on Christmas Day, he fell under their control. The blood control soon shut down, and he regained awareness, along with his children. (TV: The Christmas Invasion)
