Before Gwen Stacy died she and Norman had a little something on the side which led to Gwen being pregnant. Then she gave birth in France and had twins which were born early but fully grown babies, Sarah and Gabriel. Then Norman, after Gwen's death and aware of the situation came to raise them and convince them that Peter Parker was there father and Spider-man killed their mother. Which made the twins want revenge. They both were born with the goblin powers in their system and because of the goblin accelerated healing made them age a lot faster. Sarah is the smart one and also she looks just like her mother.

When full grown both of them went to get revenge on who they thought was their father. After a long fight over and over peter convinced them that he was not their father. Gabriel figured out that their real father was the Green Goblin and took the family's business and became the Gray Goblin. Sarah objected and in the end the battle was taken to the bridge where their mother had been killed. Being thrown off the bride like her mother Sarah fell to her doom. She was saved by Spider-man twice the first was when she fall off the bridge and then Spider-man donate his blood to her cause she lost a lot of blood cause of a bullet wound. Her blood would only accept Spider-Man's so that's why he donated it.

Sarah went back to France and according to the authorities she tried to kill herself. What really happened was that she had growing pains because of her accelerated growing because of the Osborn gene in her. that's why she had to take pills to relieve the pain. When Spider-Man got there she explained that the pills were given to her because when she was younger she and her brother got along with the wrong crowd. Another secret she was keeping was her brother in her house where he was suffering a lot of pain. Mary Jane arrived just when Sarah confessed to peter she was in love with him and kissed him. http://image.comicvine.com/uploads/item/2000/1480/25500-gwen-stacy_400.jpg
