What If Petunia Dursley Was a Witch? (Slytherin Timeline) Harry Potter Alternate History

What if Petunia Evans received the Hogwarts letter? Sorted into Slytherin as a Muggle-born during the First Wizarding War, Petunia's story is darker, stranger, and more heartbreaking than anyone imagined. This is the complete alternate history of Petunia Evans: her years surviving Slytherin alongside Severus Snape, her bitter estrangement from her sister Lily, her retreat into the Muggle world — and the night she returned to Godric's Hollow and changed everything. Told across decades from 1969 to 1988, this is a story about survival, sacrifice, and what it really means to protect someone you love. If you watched our Dudley Dursley video and wondered why he turned out to be a wizard — this is the origin story. Every script on this channel is written and voiced by hand. No AI narration.
