Last time:

He reached the still unconscious figure and started pulling clothing off, he needed to heal the wounds caused from the final charm Voldemort had thrown. He gasped in shock as he slowly revealed the body of a woman. Pushing that aside in his head, he healed the deep wounds as best he could, the last step was the potions. He gently pulled the mask away from the female and almost fainted "Miss Granger"

Now:

Severus watched the girl sleeping in his bed. Best friend of Harry Potter turned death eater. He shook his head at the sight of her battered body, "Stupid girl" he said over and over again as she would twitch from the curse. It had been 5 hours since he had brought her to his room , 5 hours he had sat in that chair waiting for her to wake up, 5 hours his mind spent reeling over the entire situation.

He had dozed off at some point while waiting for her to stir, and when it finally happened it had been nine hours since the end of the meeting. His head snapped up at the sound of a female voice, swearing like a sailor.

"Miss Granger" he said not missing a beat. "I believe you have some explaining to do."

Hermione hung her head, she knew she would have to tell him or he would go to Dumbledore, ruining her months of planning.

"I will tell you what you need to know, but first I need to get down to the sub dungeons." Severus quirked an eyebrow, as the whimpering girl climbed out of the bed.

"What could you possibly need down there?" he asked with curiosity

She ignored his question and started to walk out of his rooms, Severus walking close behind her. They reached a far corner of the dark, dingy dungeon and she muttered a spell, causing the wall to slide over.

Severus was floored at what he was seeing, but continued to follow her into the room.

The lighting in the room was dim at best, the walls lined with books, four cauldrons bubbling on a table in the corner, a wall full of potion ingredients and a cabinet stood alone from everything. He watched as she walked to the cabinet and pulled out a vial of florescent blue potion, gulping it down in one shot. Her body arched and rose from the floor a few feet, before slowly dropping back down.

She experimentally moved her arms and rolled her head, pulling up the long shirt Severus had dressed her in, looking at her body. His eyes washed over her body, noticing all the cut and scratches were healed and faint in color.

"What the hell was that?" he yelled, mind in overdrive.

She glanced up at him and smiled, " A healing potion I created a few months ago."

He shook his head at the witch, "You have more to explain now" gesturing with his hand to the room around them.

She conjured up two black leather chairs, and sat in the first one, while he moved to the second.

"What do you want to know first?" she said in a bored voice

"How long have you been a death eater?" he asked first

"six months" she answered.

"Okay, a simple question, why?"

"I joined six months ago to protect my family and Harry." she answered shortly

Severus was irritated "Care to elaborate?"

She sighed " I learned that Voldemort was targeting my parents, so I went to Lucius, told him I had information for Voldemort." She paused "Lucius doesn't remember any of it, so don't bother to ask him"

Severus was a little shocked that she had gone to Lucius, that was a big risk in it self.

"I told Voldemort that I would spy on Harry if he stayed away from my family."

Severus gave her a disgusted look "So you'll trade Potter's life for your family when you know we need Potter to maintain some sort of peace in our world."

Hermione rolled her eyes "Of course not, I only give Voldemort trivial information, things he could find out from any other student. I will only slip him something good when I know Harry wont come to harm from it."

Severus nodded in understanding "Does Dumbledore know?"

She shook her head quickly, "No body knows except Voldemort, myself and now you." she looked to the floor "I also have an advantage of possibly knowing what old voldie is planning on Harry, giving me time to warn him."

"So your playing double spy?" she nodded in response

"well...Miss Granger, I wont report your activity to Dumbledore as long as your willing to take an oath that everything you say is true. I need to make sure Potter is safe as well and will not let him die because I trusted a Gryffindor."

Hermione chuckled "I will take an oath, but I want you to take one as well – I don't want my cover blown because I trusted a Slytherin."

"Very well Miss. Granger, Now, tell me about all this and the potion you drank."

"I found this room one night when I got bored about two years ago. I set it up so I could brew in secrecy. The potion I just drank was one I started working on in third year, I perfected it three days before going to Voldemort – it heals almost everything that can be caused by a curse or hex."

Severus's jaw dropped "I'll want to see your notes, the potion could benefit me as well."

She nodded and walked over to the far wall, she tapped her wand three times on the blank wall and a small safe appeared. "I keep my notes in here -- no one can get inside but me."

She pulled the notes from the safe and handed them to Severus, who instantly started to flip through the notes. "How did you get the ingredients to mix with out exploding." His mind reeling.

"If you add the second while the first is boiling, it cause a reaction like putting water in boiling oil – but if you combine it while the first is just warm, it mixes nicely."

"This could help a lot of people you know – Poppy would be thrilled." he said while still reading the notes.

"I know it will, but for now – I plan to keep it secret, the death eaters need no extra help." she said with a slight sneer

"Why haven't you told Albus about your position?" she laughed

"Do you honestly think he would let me , an 18 year old Gryffindor female, best friend of Harry Potter, not to mention Muggle born, go anywhere near Voldemort willingly."

He sighed, "I suppose not."

"Professor, why are you being so nice to me?" she finally asked, raising her eyebrows

"Because Miss Granger, as far as I'm concerned – we are in the same boat as far as this war goes, not to mention after seeing these notes, I'm must admit that I'm impressed."

she smiled at the compliment and the pair continued to talk for a while longer.

"As much as I'm enjoying this conversation, I need to get back to the common room, everyone is already getting suspicious of my absence and I really don't need any hassle."

Severus actually chuckled at the remark, "If theres a problem, just tell them that you were helping me in my labs – I will vouch for you."

"Thank you professor, You can continue looking at my notes, but please make sure no one else sees them, I'd hate to spend so much time on the potion just to have someone else claim it."

"They will be well looked after, I will return them to the safe before I leave."

She glanced at the open safe "Just tap the center brick above it, that will close and lock it"

She turned and left without another word – leaving Severus to the notes.
