Nerys

Nerys was a guest at both of Donna Noble's weddings.

Donna assumed that Nerys had arranged her transportation from the Church to the TARDIS. When Donna finally got to her reception, she was not amused to find Nerys moving in on Lance Bennett. (DW: The Runaway Bride)

Donna mentioned Nerys again when the Doctor encountered his daughter, Jenny. Donna described how Nerys got pregnant with twins using a turkey baster. (DW: The Doctor's Daughter)

Nerys later attended Donna's second wedding to Shaun Temple, complaining about the dress she wore. However their relationship appeared to have improved. (DW: The End of Time)
