All Georgie Payne wanted was a small, but loving family, but fate had other ideas. During a trip to the Philippines, she was approached by a couple to become a surrogate mother for their next child. Georgie was a kindred spirit and never refuses a call for help, so she agreed. For nine months, Georgie lived with the couple, occasionally babysitting their months-old baby. During that time, she fell in love with the husband, James, and vise versa.
After the birth of the child, a healthy baby girl named Diana, Liza forced Georgie to go away and stay away, obviously threatened. Instead, James chose Georgie and tried to run away with both his children and his new love.
Liza had sort of accepted the fact that maybe James would want to leave, but there was no way anyone was taking away her precious daughter from her. Managing to track down the car they were using to escape, she followed them and shot at it. A crash happened and everyone managed to escape relatively unscathed, except for Reyna. James, Georgie, and Diana were able to escape. Though it was incredibly painful to leave an injured Reyna without knowing what would happen to her, he knew that her mother take care of her. After all, maybe it was too much trying to take both children away from their mother.
James, Georgie, and Diana ended up in Geithoorn, Netherlands and started to build a life for themselves there. Diana remained blissfully unaware of what her conception and birth had caused. Georgie, on the other hand, felt very guilty for tearing James' family apart and knew that he missed his ex-wife and first daughter. This caused her emotional stability to begin to deteriorate, something James had noticed. Diana was puzzled, her mother had started to stop playing with her, which was very odd. Time and time again, father and daughter would try their best to cheer her up, but their endeavors remained fruitless.
The last straw came when James had announced that he and Liza were now in good terms and are good friends. Good friends, that was the last clue Gerogie needed to put all the pieces of the puzzle together; she really did ruin James' family. Despite promising her daughter Diana that she'd never leave her alone, the guilt completely ate through her and she hanged herself that night, while James and Diana were out.
Diana was the one who discovered Georgie's lifeless body hanging from the ceiling, and it shattered her. Her father tried to shield her from the horrific scene but the damage was done. She didn't speak for weeks and had chronic nightmares about it. In an effort to lessen the numbing pain, Diana constantly lied to herself that the woman who died was simply a doppelganger of her mother. Her real mother was out there, and they were playing a global hide and seek.
Things started to look up when Diana was introduced to her older half-sister and her stepmother. Liza wasn't a replacement for Georgie. Rather, she was a new person Diana could look up to. Skype call times became Diana's most favourite time of the day, because it was the time when she could interact with her sister and her stepmother. They helped distract her from the pain.
Hearing that Reyna was going to school at Hogwarts, Diana had begged her father to bring her to Scotland so she could go to school with her. Luckily, he said yes. And here she is now!
