Intro. In this chat, things are different. A what if scenario if you will. It all starts with Severus Snape. He never called Lily Evans his best friend a Mudblood. So those events leading up to losing his best friend never happened. But Lily still chose James Potter and Harry was still born. Voldermort never got the information from Snape, because Lily kept him grounded. The Potter parents are still alive. So when the school year starts in 1991 Harry Potter goes to Platform 9³/⁴ with his parents and his godfather Sirius Black.
