Finally, she had done it. It was difficult, but she managed it. Hermione Granger had finally figured out how to use a pensieve to change the past.
Hermione had been on the run from Voldemort's forces for the better part of a decade. Ever since everything went wrong.
.:Flashback:.
"Reducto!" screamed Hermione.
The spell rushed towards Bellatrix Lestrange, the woman who killed Sirius, killed Neville, killed Charlie.
Bellatrix threw up a shield and sent back a Killing curse. Hermione threw herself to the side and cast a piercing hex. Bellatrix once again threw up a shield while Hermione ran in closer. As soon as Bellatrix's shield dropped, Hermione cast a 'Reducto' again. This time at point blank range. Bellatrix's chest exploded in a bloody mess.
Hermione stood their dazed until she heard 'Avada Kedavra'. She turned around and saw, behind the sickly green jet, Voldemort.
She froze up. She couldn't explain why but she did. And that's when everything went wrong.
"NOT! HERMIONE!" yelled Harry as he jumped in front of the killing curse. With a thud Harry's body landed on the ground. His eyes dull and lifeless.
She had grabbed Harry's body and portkeyed out and had been running ever since.
.:End Flashback:.
It was a simple modification really. All you had to do was alter the runes allowing you to view the memory to allowing you to interact with them therefore changing time. Theoretically.
She had chosen the perfect memory. It was the day after the Tri-Wizard champions were drawn. She entered the pensieve hopefully to avoid a future that ended so terribly.
