Part Three: Black House and Beyond

Severus Snape was, to say the least, relieved when Abigail White, one of the few Potions experts (she could easily be a Potions Master at any school for the Witches and Wizards) that even rivaled Snape's own personal level. She, of course, ran a shop that supplied only prime ingredients and even had already prepared potions that were of the highest level that could be accomplished and stored on shelves for any length of time.

"Thank you for coming White. Did you bring the ingredients that I need?" Severus greeted in his usual voice and she nodded a little.

"Naturally. And only the best," she added.

Severus took in her looks and mentally flinched. She had not done well with Regulus's death, though he had not done well after Lilly's death. He hadn't pulled out of it and she hadn't either.

"Sucks, doesn't it? Losing the one person you could ever love?" Abigail inquired very quietly and he glared a little at her, as a warning, before dropping it.

She waved her hand and he swept out, dressed in black robes and she followed with a slight swish of robes of emerald. She smiled a little and set her own cauldron up in a parallel room to his.

She moved her supplies into her own room, but the large cauldron she had was set up where she wanted it and she moved things to her wishes. She looked out when she heard a crack and smiled. "Hey Kreacher," she greeted softly and his ears perked up slightly.

"Miss Abigail," he greeted happily, wringing his hands.

She kneeled down slightly and smiled at the House Elf. "Could you do me a favor?" she asked softly.

"Kreacher is always happy to aid Miss Abigail," he answered happily.

She nodded and had him bring her a light lunch. She spent her days out of sight, mostly, just helping Severus. She got along with him, the best, out of everyone there, omitting Kreacher, and then she saw Lilly's eyes one day.

She blinked and stared. "You must be Harry," she stated simply and it made everyone jump.

"Abigail! When did you get here?" Sirius asked and she gave him a look.

"When I was supposed to."

"Abigail! I haven't seen you since the First War," Remus stated and she sent her eyes heavenward in annoyance.

"Defiling my Mistress's house," Kreacher muttered and she looked over at the House Elf, then back at Harry.

"Yes…you know, they say the eyes are the window to the soul," she commented, loudly, and left.

Harry stumbled across her two nights later, sitting next to the Family Tree, one hand holding a glass of Fire whiskey, the other hand supporting her chin. She looked over and smiled. "Hello Harry," she greeted and looked forward.

"How did you know who I was?" the Boy Who Lived asked.

She almost retorted, but stopped. "A friend, a friend I made shortly after the First War ended, writes to me all the time. We keep in touch and wrote to me about you. Said some mixed things," she answered quietly, staring at Harry before having her eyes drift over to the Tree again.

"Who?"

"Can't say. Ask the question you want or go back to bed."

"What did you mean, when you said 'eyes are the window to the soul'? I would bet everything I own you are like Lilly," she answered with a soft tone.

Harry stared and she looked back. She slowly stood and stated, "Ask Severus about your mother, but no one else who you look up to could. Maybe your Head of House, but I doubt it. Ask Severus some time."

She then slowly stood up and walked out, then down to her Potions Lab, or her temporary ones at least. She rolled her shoulders slightly and pulled out her old Potions Journal.

In the cover was a Wizarding Photo of Regulus, hugging a Photo Abigail and smiling. She was looking up at him and they twirled around in the falling snow. She watched before gently shutting the journal and finishing off her glass.

She fell asleep rather quickly that night.

Harry stared at the locket, the fake. He turned it over and opened it again, ready to throw it almost, before he noticed the engraving. "Kreacher…did Regulus have this engraved?" Harry suddenly asked of the House Elf who was standing next to him, wringing his hands a little.

"Yes, yes. Master Regulus had it engraved for Miss Abigail. For their anniversary. Originally, he was going to give it to her, when…he saw what happened to Kreacher, he used it to switch out," Kreacher answered.

Harry closed it back up and handed it to Kreacher. "Here, have it Kreacher. Do with it what you will," he stated and Kreacher seemed to have his eyes water with glee.

Harry never told Abigail about the locket.
