Nat: Alexia Gibb

Nat first appeared in episode 9 of the 1997 series. Introduced as Ollie's sister. Nat made friends with Harry although her initial motives were highly questionable.

As Harry's friend, Nat was involved in Harry's affairs after Harry's father's girlfriend, Jill showed up; she was looking for Harry's father as she was in some sort of trouble. After she learned about Harry's money she tried to get it off her on the pretense she needed it for her unborn child who would've been Harry's half-brother/sister. However, Nat saw through Jill's act and discreetly gave her false information that she hoped would teach her a lesson but actually resulted in Harry getting kidnapped and locked in a cupboard.

Nat tried to rescue Harry later, but Harry was perfectly safe as Jill had released her and explained that there was no baby but she really needed the money because Harry's dad had borrowed money off a rather sinister loan shark and they were demanding money that Jill didn't have on threats of violence they intended carrying out. Harry agreed to give Jill the money she needed and promised her she'd come and visit her at her new home.

Nat and Harry later lead the Grove gilrs against Ollie's Network O and supported Terraise (Tyneside Tina) against Karen, Sita and Cher.
