Abigail Oblong-9 Menton

Abigail Oblong-9 Menton was a member of Uncle Lindsay's casino whose name Amy used after arriving in the Sphere. Abigail was having her calves restrung in the Caroline Spa when Amy met Uncle Lindsay.

Amy went by "Abby" whilst on the Sphere and continued to use the name afterwards, no longer going by the name that the Fifth Doctor gave her. (AUDIO: The Sphere)
