During the "War of the Symbiotes" storyline, Gwen/Carnage's back story in the Triskelion is revealed. It is shown Gwen has been taking some form of therapy with Tony Stark. However, when the Green Goblin broke out of the Triskelion, Gwen escaped and went to Peter Parker's house in a confused and terrified state, with Carnage's face on her body. During an exchange between Peter and Gwen, Eddie Brock attempts to attack Aunt May and retake his symbiote. In a rage, Spider-Man engages Venom on a nearby rooftop. During the fight, Gwen is shown to be able to use her symbiote to fight off Eddie but Eddie reabsorbs his symbiote along with the Carnage symbiote rendering Gwen Stacy an average girl. After a series of tests, it is concluded that this Gwen is not a clone but consciously and genetically is the genuine article now reborn (though Gwen's original body died, the Carnage symbiote absorbed her being and they had bonded since her death). After S.H.I.E.L.D. intervenes, S.H.I.E.L.D. Director Danvers states Gwen will remain in S.H.I.E.L.D. custody. Peter and May argue for her to come back to live with them, with Tony Stark supporting the Parkers. In "Ultimate Spider-Man" #129, the Parkers are now helping to rebuild Gwen's life. Her ghastly experience with the Carnage symbiote also causes her to develop a death anxiety she gradually controls. Six months after the "Ultimatum" storyline, in "Ultimate Comics Spider-Man" #1, Gwen is living with the Parkers again and seems to be dating Peter. However, circumstances involving the Chameleon made Gwen realize she made a mistake dating Peter. She breaks up with him, but still lives with the Parkers due to Gwen and Aunt May has become close in a surrogate mother-daughter fashion.
