It's never over

If Lily and James lived

If James and Lily lived but Voldemort was still there, like somehow he had gotten Harry and he was the boy who lived but James and Lily's love for each other and Harry didn't get all three of them killed and they were a happy family. Harry would know "Uncle Moony" and "Uncle Padfoot" and then Peter would be in Azkaban because James and Lily would be alive to tell the story. In the first year he would know about magic, but still be the boy who lived. In the second year, right along side Ron's howler would be the one from his parents which would just be Lily yelling at him while James and Sirius laugh in the background and hijack the last part so they say they're proud of him and Remus just goes, "Sirius no!" (That wasn't mine that was from....THE INTERNET) And instead of Sirius escaping it would be Peter, but he wouldn't come to Hogwarts he would just go straight to Voldemort. Harry wouldn't be as affected by dementors. Snape would probably hate Harry a little less because Lily lived, and maybe realize that James really did love her more than he loved her. Harry might have siblings. In the fourth year they'd be really worried. In the fifth year, Lupin would be fine with Harry calling him Lupin but Sirius would still request to be "Uncle Padfoot" and Harry would eventually get annoyed. Sirius wouldn't die because James would be there to curse Bellatrix right along side him while Lily got Harry out of the way. I think Earlier Wolfstar would have been a thing but later Remus would fall in love with Tonks and Sirius would
Just be like,
"I see the way you look at her, I know we used to have something but we're falling apart now."
And Remadora would continue. In the Deathly Hallows Harry wouldn't see his family dead, since someone would have been there to help Tonks and Lupin, he's just see Dobby and Dobby would guide him to through the Dark forest instead of Lily and when Voldemort was finally gone they'd all be a family. Fred probably would have lived because with three extra lives saved they could go on to help save three more lives. It wouldn't have been the same but it would have been nice.

But if that happened, when Harry uses the stone Dobby would have just been standing there and it would have been, if anything, more tear jerking because Dobby would just be smiling
"Harry Potter. How good to see you, sir."
And Harry would just go over to him and try to hug him and say he was sorry, but he couldn't because Dobby wasn't really there. And Dobby would just hold Harry's hand, well, not really but it would seem that way, and lead him into the forest.
