If Harry's Parents Really Could Be Alive Or If Harry Had A Family
Godrics Hollow, 31st of July 1996.
Lily woke up early in the morning and wanted to go grocery shopping. She didn't have a wand and didn't know where to find the money for it so she just conjured up some easy breakfast. The others weren't up yet, and she didn't need them to be, she was going to find her sisters. She found an old broom and after only ten seconds in the air she decided that they needed new brooms. She flew on, though, away from the Potter Mansion and towards Evans1 (Her sisters hadn't married by the time they had died and lived in Evans1 and Evans2.) Her sister Violet lived in Evans1 and Lily hoped to find her there, alive. She barged in the front doors and found her two sisters waiting for her. She ran over to them, crying freely, and hugged them tight. Some way or another they managed to get on the single broom all three and fly over to the Potter mansion where Lily's family waited at the breakfast table. Violet and Dahlia hugged James and the twins and they all seated themselves to eat. After breakfast the six went to visit Dumbledore and told him everything. Luna and Cassie would start Hogwarts on September first. He told them where Sirius and Remus lived and where to find the Minister of Magic. He also informed them of the fact that Petunia had Harry and that she still lived in the same house that she had lived in fifteen years ago. After that they went straight to Arthur Weasley, the Minister of Magic, and told him everything. He believed them and told them to not tell many more people till he told them to. They were only going to tell Remus, Sirius and Harry anyway and told him that.
"But Harry's staying with us this last month, and Sirius and Remus are arriving there about now for safety reasons." Arthur said.
"Harry's staying with you?"
"Yes. My son Ron, his girlfriend Hermione, my daughter Ginny and Harry are friends."
"Oh. Well. Could we go over to your house then? But we'll need some wands. We don't know where ours is."
"Well I have them. The last Minister had them kept for safety. I can find them for you and see if they still work with you. And of course you can stay with us. No problem." Arthur walked out of the office and came back with four wands.
"We'll have to take the two girls with us to Ollivander. We can trust him. Come with me." Arthur went over to the fireplace after handing the wands to their owners who got sparkled with sparks in different colours. He took a pinch of floo powder and threw it into the fireplace. One by one the entered, yelled "Ollivander Wands!" and entered the wand shop through the fireplace. The owner did not seem surprised to see them. He brought out several wands for the girls to try. Cassie found her wand first. 8 ½ inches, inflexible, of yew and a Veela-Unicorn twist, pretty good for transfiguration and charms. It sparkled out in golden and silver sparks. Luna's was rare as well, Mermaid-Unicorn twist, springy holly, 11 inches. Good for transfiguration and charms this one as well. As with Cassie's it sparkled out golden and silver sparks. Lily, James, Violet, Dahlia, Cassiopeia and Luna waited at Ollivanders while Arthur took out some money for the Evans' and the Potters, not from Harry's vault though, from an even bigger security vault Lily and James had put up for when they returned. He came back and they flooded right to The Burrow. But the Burrow looked nothing like the Burrow at all, not like they would know that. It had been rebuilt and was now a mansion like the Potter Mansion and the Evans1 and Evans2 mansions. They were placed in some bedrooms on the third floor to rest a little while Arthur told his wife the story. When they woke up Arthur led them to the third year living room where Sirius, Remus and Harry were waiting.
"Harry." Arthur said, "I believe you have one more birthday present which wont need opening, one which I hope Sirius and Remus will enjoy as well." He stepped aside and let Lily, James, Violet and Dahlia in. They had decided to wait a bit with Cassie and Luna as no one knew they existed.
"Lily?" Sirius said, "James, Violet, Dahlia? Is it really you?"
"It can't be..." Remus whispered.
"How can this be?" The four seated themselves and told the story till Cassie and Luna appeared. Then Arthur let Cassie and Luna in and when the story was over Harry said: "I have sisters, I have a family. I think this must be the happiest day of my life." And hugged the members of his family one by one.
At the same time in the second floor dining room.
"Mom," Ron asked, "Do we have guests or something?"
"Yes we do. And I don't think you'll ever be able to guess whom. They are guests of Harry."
"But I already know Sirius and Remus are here."
"He have more guests then them. He actually has six more guests. And I want all three of you to be polite." Molly said looking pointedly at the three teenagers standing in front of her.
"And I don't want any of your jokes!" She yelled to the twins across the room.
"Bill and Charlie will arrive soon, as will Percy and Penelope. Will you go greet them and help them get their luggage up to their rooms?"
"Yes mom." Ginny said and dragged Ron and Hermione down to the 1st floor fireplace. Precisely half an hour later all the Weasleys (minus Arthur) and Hermione and Penelope seated. Arthur came in the doors.
"Now children. I will not tolerate any rude pranks at this meal, or any panicked escapes. The people you see coming in these doors soon are real. They are not dead, but alive. OK?" All his children plus Hermione and Penelope nodded.
"First the birthday boy Harry," Harry came in and seated himself opposite Ron, who sent him questioningly looks.
"Sirius Black and Remus Lupin." Sirius and Remus came in and placed themselves on one end of the table.
"Harry's aunts, Violet Evans and Dahlia Evans." Violet and Dahlia came in and earned approving looks from all the males (Something which earned both Ron and Percy a slap on the shoulder).
"And everyone stay seated. James and Lily Potter." The whole lot of Weasleys (plus Hermione and Penelope) sat gaping as Lily and James entered and seated themselves one seat from Harry on either side. Harry smiled at his parents and hit Ron's leg with his foot to make him stop looking like some dead fish.
"And last but not least Harry's sisters Cassiopeia and Luna Potter!" They entered and seated themselves next to Harry while everyone looked like lightning hitting the table next wouldn't be out of the question. Arthur seated himself, clapped his hands and food appeared on the table. And while everyone slowly ate their food the Potter's and Evans' explained everything.
