As ever, standard disclaimers apply.
Remus Lupin apparated to an ally near the Tube and used Muggle transportation to get to his destination. Moody had reminded him that it was better to be safe than tracked by Death Eaters. Constant Vigilance! Not wanting to get into an argument with the older wizard he decided that it couldn't hurt to follow the ex-Auror's advice. It was still bright when he arrived at the clinic, but there were no more patients and Hermoine was standing just inside the door watching for him. She unlocked the door and ushered him inside. She wore a concerned look that made her seem far older than mere teens.
He smiled as much in greeting as in an effort to alleviate her anxiety. "Are you coming as well, Hermoine? I'm sure Harry and Ron would be very glad to see you; and Ginny too."
"Oh! Yes, yes, I'd like that. Mum and Dad are just inside," she gestured and led him back to the inner office.
The senior Grangers looked up from the computer screen. "Look here, I think your Death Eaters have made the evening news."
"What?" Remus angled in for a better look. There was some sort of moving picture in a small window superimposed on the bigger window, "What is this?"
"Video feed. 'Small village in the north suffered major loss of life when local petrol station exploded for no reason, earlier today' " Hermoine's father read. " 'Local amateur captures images on video camera.' Watch." There was silence as a green cloud emerged over the dark soot of the earlier explosion. It slowly coalesced into a skull with a snake emerging from--
The image looped back to the start. "No one's commented on it, though." Granger sounded confused.
"They don't see it. Muggles mostly ignore magical incidents completely automatically.
"Grace and I are Muggles, even if Hermoine isn't."
"Ah well. You know better. Are you ready?"
"Quite." The man picked up a small case.
"Mum, dad, Harry and Ron are there. I'd like to go with, please."
"Well..." Hermoine's mother glanced at the computer screen looking very uncertain.
"I can assure you that the safe house is very much that. More than safe even, it has been magically hidden with one of the most powerful charms--"
"The boys are there? And other adults?"
"Most assuredly, Dr. Granger."
"Very well, Hermoine. Please be careful, though."
The Grangers shared a quick kiss. Remus took Hermoine's hand and Dr Granger's and apparated with the underage witch and her Muggle father to the same spot as he and Madame Pomfrey had done when they had retrieved Snape. "It's a tad run down," he tried to warn the other man, "but you should have seen it when we first got here!" He hustled them to the door which opened at his request.
Mrs Weasley had been pacing the entrance hall and was right there to greet them with a smile of genuine affection. The portrait of Mrs Black, however, greeted the three with shrieks of rage and insults until Molly Weasley smacked her frame with a stirring ladle. "Sorry about that," she apologized without registering Dr Granger's complete shock at encountering a talking -- well, screaming in this case -- painting. "We have got to get that thing removed. Hermoine! Everyone is down in the kitchen. Doctor Granger, I'll take you upstairs."
Remus shared an amused wink with Hermoine, but followed Molly and Granger up to Snape's room. Not unexpectedly, the room was quite dim. Sitting beside the bed, coaxing yet another potion tainted tea into her patient, was Madam Pomfrey. She looked up, giving the man a speculative once over before she rose to greet the Muggle healer with a polite nod. "I am Poppy Pomfrey, Hogwarts' school nurse. I must admit, I've never seen a blood letting," she didn't seem very enthusiastic about seeing one now. "I'm told that method of healing hasn't been practiced by Muggles for several hundred years! You won't be taking too much, though. "
Poor Granger looked very askance at this suggestion. "This is not 'blood letting,' Madame Pomfrey. I am just going to remove a small amount of blood with a syringe to have it tested."
The witch gave him somewhat disbelieving look. "I know you Muggles use syringes to introduce your potions directly into the veins and muscles. I had no idea you used them to withdraw blood as well. But of course it does follow. A draw instead of a push. I shall observe. Severus is my patient after all."
Granger smiled weakly and moved further into the room. He was quite visibly startled at the appearance of the man in the bed. "I'll need more light," he requested barely above a whisper.
"Lumos," Molly obliged him without comment, bringing up to full the sconces on the wall, and went to stand next to Poppy on the far side of the bed. Remus merely stayed out of the way.
Dark eyes stared out disconcertingly at nothing, but as the man moved in, the obsidian stare seemed to settle on the encroaching figure. A faint expression of concern almost appeared on the gaunt face.
"Now then, erm... I'm not going to hurt you, well actually that's not strictly true, ah... I'll just get on with it, shall I?"
Molly exchanged an uncomfortable look with Poppy. "You've not done this much, have you?"
Granger had his case open and his head was bowed, looking inside. "I'm a dentist. We don't actually have much cause to draw blood. Really a nurse... erm, a regular nurse or a technician would have been a better choice. But I understand you don't have that option." He looked up, having located everything he needed, and began laying things out on the nearby bedside table. "I'll need a vein." He turned toward the man and brought his arm out from under the covers. There was no resistance, not even the slightest tensing of muscle. A look of horror passed over the man's face as he beheld the scars that disfigured the pale skin. But he caught himself and regained his professional mask. There was not even the slightest reaction when he wrapped and tightened the plastic tube around the pale arm so as to force a vein to protrude. There clearly was no sense asking this Severus fellow to make a fist. He swabbed the whole area with alcohol soaked gauze.
There was an intense silence while the Muggle dentist tried to find or force a vein. Minutes passed and he was getting a bit concerned. The scarred flesh was more than a little disturbing and he was no longer so sanguine about the wizarding world that was claiming his only child. But he left that train of thought knowing it was too late to force her back. Not mention, he'd now involved himself and why couldn't he get a vei--? "Got one!" he muttered at last. He brought the needle up.
Mindless cooperation disintegrated with a sharp cry as Snape contorted and pulled himself away from the glass and metal gleaming evilly at him. Dark eyes widened with terror, held fascinated by the thin weapon. His voice, little more than a hoarse croak, screamed wordless protestations while uncoordinated limbs flailed violently. A terrified "No!" echoed just before a crack of thunder pealed and lightning inundated the room.
Granger, Lupin, Pomfrey, Weasley, all became projectiles unable to control their violent flight.

The tranquility of nothingness writhed weakly once again as grey shapes impinged on his awareness. He didn't care. He didn't look. He accepted they were there and would go away if he didn't bother acknowledging them. He tasted something bitter and it almost grabbed his attention, but just in time did he remember that he wanted nothing to do with the Outside. The Other might be there and though he was certain there was nothing else that existed but himself. he did not want to disturb the peace that was his existence now.
But that was not to be, for after some time (which he didn't measure after all time did not exist) something sharp invaded his grim tranquility. Something that glittered and threatened to destroy Everything in a blinding surge of agony --
"No!" Away! Go away!
He shoved the attacking Paingiver away with every iota of his being.
--
"Ouch." Remus opened his eyes to find himself squashed in an ungainly sprawl against the hallway wall. He'd been flung clear out of the room!
"What... What happened?" Dr Granger's voice wobbled as did his legs when he picked himself gingerly up from the floor . His head was pounding and he was surprised to find himself near the wall next to the room's door. He felt someone take his arm and he forced his eyes to focus on Hermoine looking fearfully up into his face. He patted her head and winced. "I'm all right... What was that?!" He squinted at the unsteady forms of Madame Pomfrey and Mrs Weasley, though he wasn't quite sure what was accounting for the swaying; their own unsteadiness or the spinning room.
"Wandless magic, that was." Tonks explained brightly. Everyone in the house was trying to cram into the small room.
"Ugh" grunted Remus. "Molly, Poppy--?"
"They're a bit stunned," the young Auror told him. "Much like you and Doctor Granger." Chairs had been conjured or transfigured and all four of the victims were being settled into them.
"I don't think I even got near... Where's the syringe?"
"I saw something flash near your hand," Molly said weakly. "I think it's disintegrated." She tried to smile at Ron who was leaning over her looking quite worried and not a little put out at the attack. "You are not going to try that again, are you?"
"Erm... Not unless we can sedate him!" Hermoine's dad answered fervently.
It was Ginny who noticed the professor seemed again oblivious though he was twisted and tangled in the bedclothes as if he'd been hexed by an entrapment spell that hadn't gone off quite right. "He looks like he doesn't know what he did." She said with a frown.
"He doesn't, dear," Madame Pomfrey assured, her voice back to its unwavering timbre. she took a deep breath and looked around the disheveled room. "It would seem that most of the fury was directed towards Remus and Doctor Granger." She observed.
"More like the needle." Remus said shaking his head. That wasn't smart, but it could have been worse. The room had been beginning to settle down before that.
Footsteps suddenly came clumping up the stairs. Arthur Weasley, back from his long day at the Ministry poked his head in and frowned at the gathering. "What's all this, then?" he moved over to Molly's side and bent to give her a concerned little kiss.
"Professor Snape didn't want his blood removed, Dad," Ginny explained characteristic terseness. "He did wandless magic. We heard downstairs!"
"Bloody shook this house on its foundations, I should think!" Granger added.
"So now what? We can't give up--"
"Oh no, of course not, Remus, and I don't know why we didn't think of this before, Poppy. We'll just put him to sleep." Molly rose and moved over to the bed. She brought out her wand and touched it to Snape's temple. "Dormio" she murmured gently. The dark unexpressive eyes closed and the Potions Master's body relaxed.
Dr Granger managed to successfully get several vials of blood though he wasn't as proficient as someone more properly practiced would be and he managed to push the needle a little too far, "Going to bruise there," he muttered. But Madame Pomfrey tutted and said something about fixing it up when he was through. He labeled each vial and let the nurse disintegrate the used needle. "Now we just need to get this to the lab and back." No one could helb but notice how relieved the man was now that the task was finished.
