Hermione quickly wiped away the tears and turned toward the voice. She wasn't shocked to see Neville there in front of her. During the final battle he had saved her life and she offered to do anything to pay back the life debt he owned. He didn't want anything. Well, thats what he tried to tell her anyway.
Hermione looked around the Great Hall in search for Neville. She needed to thank him. She was battling Dolohov and Rowle was sneaking up on her. They saw it as the perfect time to get rid of the brains of the Golden Trio. Before she could blink she looked up to find Neville on top of her and to dead death eaters.
"What happened?" A confused Hermione asked while trying to catch her breath.
"Well they killed each other because I jumped in to save you when Rowle sent a killing curse at you back. Now, get back to Harry." Neville disappeared in a blink of an eye.
She finally found him sitting on the steps out in front of the castle. She walked slowly and sat down beside him. He gave her a smile and turned back towards the grounds.
"Thank you Neville. What can I do in return?"
Neville blushed and stated, "You don't need to do anything for me. I only want one thing…" he faded off in embarrassment.
"What is it Nev?" Hermione coaxed.
"I always wanted a sister. Someone that I could look after and protect."
"Do you want a blood or adoptive?"
Neville smiled. "Either or. I just want family. Gram won't last forever. I would be the only Longbottom left. I want a little sister to spoil and to protect. Age doesn't matter."
Hermione looked deep in thought and turned to Neville.
"Anyone in mind?"
Neville mumbled something under his breath and blushed again.
"What was that Neville? I didn't hear it."
"You," was whispered in a quiet voice.
Hermione smiled to herself before wrapping her arms around Neville in a hug.
"I would be honored to be your sister. I have to research a little to find a spell that legal and see all a family bond holds. I don't have a family anymore. I sent my parents away by obliviating their memories and know there isn't a chance for them to get them back."
Neville nodded his head and pulled Hermione closer to him. Family was the most important thing to him and he knew that his Gram would love to have Hermione in the family.
Hermione found a bond. One that was more like a twin bond than anything. They could feel each other's emotions and at times read thoughts. More power rolled off both of them but they never seemed to notice.
"Hermione, princess, what's wrong?"
She launched herself at him, more tears flowing down her face. He just held her, letting her tears be soaked up by his shirt.
A/N: For the sake of the story Hermione was born in 1980 instead of 1979. I wanted Neville to be older than her and that was the only way. So She started Hogwarts at age 10 turning 11 eighteen days after school began.
