George Thompson

George was a Tenza child who used a perception filter to convince Alex and Claire he was their son. When George was afraid, he put his fears into the doll's house in his cupboard, where they turned into Peg Dolls. One night, he overheard his parents talking about sending him to see a doctor about his fears. George misinterpreted this for rejection of him, causing the Peg Dolls to begin kidnapping people and stealing things that scared him. Eventually, his fears sent a plea for help to the Eleventh Doctor's psychic paper.

When the Doctor arrived, he tried to help George face his fear. He deduced there was a powerful alien presence and the monsters he feared were real. When he opened the cupboard to face these monsters, he found nothing. He realised what George was and forced Alex to remember that Claire could not have children/ George became frightened and the Doctor and Alex were sucked into the cupboard.

As the Doctor and Alex were being attacked by the Dolls, the former shouted out to George to take control of the situation and face his fears. He appeared in the doll house as well, but was also attacked due to his lingering fear of abandonment. Alex rushed towards George tp protect him from the Dolls, assuring him that he was his son and would not be abandoned. Everyone was subsequently released from the doll house and returned to normal, while George continued to live as a normal, happy boy.

The Doctor promised to return when George was going through puberty, "always a funny time". (DW: Night Terrors)
