After having a short experience with the Elder wand Hermione wanted to know as much about wand lore as possible along with other subjects and Severus' library was perfect for finding information. Hermione had secluded herself to his library only leaving for food or the bathroom. Plenty of times Severus had shooed her out so she could sleep in a bed rather than on the floor or the uncomfortable sofa.

After five months Ron was still on the run and Hermione had read three quarters of Severus' library. Severus didn't think it possible for anyone to do such a thing but this was Hermione. She lived and breathed books, and that photographic memory probably had the pages of the books she'd read memorized to recall information. As her teacher he'd long figured out that she had a mind palace, she had room in her mind for specific information that allowed her to recall it when necessary.

He also observed that her power was increasing exponentially, which normally would be a problem for most wix. Hermione though had realized the more she strengthened her magic the more she'd have to strengthen her body. She was still curvy but Severus could see the slight muscles that were becoming more defined from her daily exercise and he approved greatly she was taken great care in herself. He found that less and less he had to remind her to eat or sleep. Many a time he found her out back practicing the spells she had learned. Though she was keeping mostly to herself she was happy and that's all that mattered.

Severus sat in his study reading a new potions journal. He was finding it a waste of time and was about to throw it into the fireplace when Hermione crept into the room. Severus moved aside on the sofa, allowing her space to sit.

"Severus, do you think it would be okay for me to visit Olivander?" She asked as she sat next to him.

"For what exactly?"

"I want to know more about wand lore. Your books are extensive on the subjects but I think it would be better to learn from someone who deals with the subject." Severus understood. After all, if you wanted information on potions you would go to a potions master.

"I can arrange for the old man to come here if that's okay. I'm sure he would appreciate some time away from his home."

"Thank you Severus." she smiled as she reached over and squeezed his hand. Hermione turned her body towards the fire and quietly sat and read the book she'd brought with her. Severus sat there a moment looking at his left hand. Her hands were soft but he could feel the physical and magical strength coursing through her. Why couldn't she have this power when Voldemort was alive? She could have easily ended him. But Severus knew that this was okay. She could use this newfound strength to do some awesome things.

Three days later Severus brought Olivander to his home. Hermione had been in the library in her most unsurprising position, sitting on the floor surrounded by books and her wild hair being precariously held up with hair bands and muggle pencils. She was so absorbed in what she was doing that she noticed neither man. Not even when Olivander hobbled over to the nearby sofa and sat down. He cleared his throat and she still hadn't moved so he picked up one of the books closest to him and dropped it in her lap thus rousing her from her reading.

"How long have you been there?" she asked surprised.

"I've only just arrived."

"Oh, I'm sorry." Hermione turned her self to facing Olivander and grabbed a notebook out of a pile and opened to a clean sheet.

"Severus has told me that you want to learn more about wand lore. There aren't many who would gladly want to learn this even though most wix are useless without one. Since I'm here, may I see your wand?" Hermione handed over her wand to Olivander. "Give me your wand hand." Hermione placed her right hand in his. He studied her hand and her wand and nodded with a furrowed brow.

"Ms. Granger it seems that you have strengthen your wand. Though it seems this was done inadvertently and this is a very rare occurrence."

"Oh, how rare?"

"Out of the hundred plus years I have been doing this I have come across only two wizards to do this. The first was Albus Dumbledore and the other is our own Severus here." He said as he turned to look at Severus who was sitting in the armchair. "Did you teach her to do this?" asked Olivander. Severus simply shook his head no.

"Severus hasn't taught me how to do this. I must admit this is my own doing from reading all the books in his library and practicing. I knew I was getting stronger but I didn't know that my wand was as well."

"Wands tend to grow with their owner. You noticed that as a student the stronger you got the better your spells preformed correct?"

"Yes."

"Good, the only thing is that this growth that I've detected in your new wand is something that happens over years not months. You're a very capable witch, and I think a witch capable of understanding wands."
