Biography
Claire was unable to have children. They took IVF treatment, to no avail. Eventually they had son and named him George. When George became frightened of something in the flat, it was placed in his bedroom cupboard. Alex could not cope with looking after him and began to wish someone would take George away. He had no job of his own, most possibly to keep an eye on George, and could not keep up with his rent. In 2011, the Eleventh Doctor visited per a psychic distress call from George.

After George displayed great telepathic powers, trapping him in the cupboard with other, Alex learned from the Doctor that George was a Tenza, but still his son. Alex's unconditional love for his boy allowed George to overcome his fears and save his father, the Doctor and Rory from the Peg Dolls. Subsequently, Alex lived a more peaceful life with his family. However, he still worried that George's alien nature may cause something odd to happen to his physical appearance. The Doctor promised to return when George was goin through puberty to help out just in case something similar happens. (DW: Night Terrors)
