Okay, so I've hit a wall with my other one. I've had this idea in my head for a while, so I'm not sure if I will continue this or not. Severus is not dead. I have guessed some names. All rights to JK Rowling.

"Now class, this potion must be made carefully. One mistake could lead to a fatal accident," he explained to His students.

"This potion will reveal any traces of magic on a person. You may brew, and then bottle it and place it on my desk," Severus Snape informed his small class of eighth years.

Very few had returned, only two of the 'golden trio' had stayed, Hermione and Harry, along with Draco, Blaise, Katie Bell, Romilda Vane and Leanne Trueblood.

They were working individually in the class. He looked up, watching carefully, before he returned to his marking. He missed the quiet sniggering between Blaise and Draco, which quickly led to an explosion. The hot potion substance went all over Harry Potter. Severus looked up just as the potion began to explode, however, he wasn't fast enough to stop it.

"Zambini, Malfoy, get out!" He growled. He had decided that he was not going to have any favourites this year.

He slowly walked over to Harry, "Mr Potter, please lower your cloak so I can see the damage. You will probably need to see Poppy."

Harry shook his head, refusing to look at the potions master. He pulled up the hood and kept it well over his face. The burns were bad, but not as bad as the truth. No one could know he was a she... That 'Harry' actually died at the hands of Voldemort, that the Potters had twins, one being a little girl, who was in the cradle with him. An untraceable charm had been put over her along with a glamor to make her look like Harry. It wasSirius who had placed the charm over her just after she was born. It was just in case anything happened to Harry. No one could know Rose's true identity.

"Potter!" Severus barked, pulling back the hood slightly. He froze at the sight before him. It was Lily, those green eyes, freckles, long ginger hair...

"Get those burns seen to. I'll take you myself," he grumbled, falling back into his role.

"Class dismissed!" He called into the room, as he led the 'girl' to his quarters, rather than to Poppy.

Once they arrived in his quarters, he spelled the door to lock.

"The unbreakable vow. Only until I am ready to talk publicly," Rose snapped back. She offered her arm to him. She could be herself, now that her disguise was gone.

"I, Severus Snape, swear on my magic not to repeat anything that is said within this room, until given permission to do so," he grudgingly said. He watched the magic over their arms, before he dropped his arm and went to sit in his chair. He summoned the fire whisky, and took a long swig from the bottle.

Hesitantly, Rose undid the cloak, dropping it from around herself onto the floor. Her body was very thin, frail looking, and she looked just like a young version of Lily Potter. She had high cheekbones, thin eyebrows and a narrow face. Her long, ginger locks fell down to her hips, though a small pair of black ears poked out through her hair.

"Lily had twins. Sirius spelled me to look like Harry if anything happened to him. Voldemort killed Harry that night and well, I became him. The potion reveals all, hence the ears and the fact I'm definitely female," she explained, rushing her confession.

She hesitantly sat in his other chair, but she couldn't' get comfortable and began to curl up, a soft purring escaping her.

"I'm a Kitsune, from my father's side, though the line has been dormant for -"

"Close to a thousand years. They're supposed to be extinct," Severus interrupted, looking her over, with disbelief clearly on his face.

There was an actual Kitsune in his quarters, and it looked just like Lily Potter. He observed her closely, and could see the burns beginning to heal on her face. The magic was strong and raw.

"You will tell the school that Harry has left, and there is a new student, myself. Unless you're going to take me on as an apprentice," she spoke rather bluntly, not expecting him to want her as an apprentice. However, she could see him not wanting to let her go far, as she did look a lot like Lily.

"I will need help either way. You see, it's complicated, the spell Sirius placed on me. It limited my magic, so I'm a lot more powerful than I'm used to," Rose pointed out a little timidly. She was not sure if she should be so honest with him.

"First things first, potions, something to eat, then you can sleep, and I will think of our options. The world isn't going to take well to Harry potter being dead and you being a girl," he reminded her gently.

He had already lost Lily, so he was not willing to lose this girl. She looked just like Lily. Maybe she could finally be his. No. Severus needed to lock himself away. He couldn't be hurt again.

"Whats your name? Unless it is Harry?" Severus suddenly asked. He stood and went to collect her potions.

"Rose Lily Eileen Potter."

A bottle smashed from the potions storage room. "What?!" Surely he couldn't of heard that right. Why would Lily give her daughter his mothers name?

"Rose... Lily... Eileen... Potter," she answered, pausing after each answer she gave. She was confused by his reaction. "Though I don't know where Eileen came from," she mumbled, more to herself. The witch momentarily lost herself in thought.

"It was my mother's name. Me and Lily made a promise as kids to name one of kids after ourselves or our parents." He answered easily. He grabbed the potions once more and placed them on the table, "Drink up. You're going to need your strength."

Reluctantly, Rose sat up and drank the potions. She pulled a face as she drank each one, suddenly regretting her heightened senses.

"Tell me about mum, please," the young kit begged. She curled up on the chair, as she looked up hopefully towards the elder wizard.

"Soon. I will soon. I'll find the photos and letters tomorrow," Severus promised her. He then stood, heading into his office to arrange his lesson plans. He returned an hour later, and found the witch curled up in his chair, purring contently.
