The older Evans sister
Severus got out of the taxi and stepped into the most boring street there was on earth. Every single house looked the same. Even the cars all looked the same. Yes, he could see Petunia Evans being very happy here. The most boring place on Earth for the most boring woman on Earth. The chatterbox of a taxi driver fleeing the scene in his yellow vehicle was probably the most exciting thing that happened here in weeks.
Petunia's house, with its perfectly kept hedges and neatly trimmed lawn, looked just like all the others in Privet drive. Warm yellow light shone through the windows, indicating that the Dursleys, how they were called now, were still awake. Hastily, Severus straightened his cheap Muggle suit and approached the front door. He pressed his finger onto the doorbell and heard it ringing inside. It was an annoying tune, like some drunk clown was drumming on a poor piano with broken chopsticks. Hurried steps approached and the door opened without any noise. They seemed to oil the hinges regularly.
Petunia's bony face angrily looked up to him. Recognition rushed over it closely followed by disgust. “Snape, what do you want from me?”, she hissed. Then her face went pale, almost as light as her blonde locks. “This isn't about Dudley, is it? He isn't... He isn't one of your kind, is he?” Her voice was barely more than a whisper now. Severus laughed and shook his head, greasy, wet hair flying around him. “Your kid? No.”, he snarled.
A look of relief washed over Petunia's horsey features. Then she immediately tried to slam the door shut in front of Severus face. It was quickly stopped by a shoe. The hard wood hurt his foot, but he managed to suppress the pain. Serving the Dark Lord was much more painful than this, anyway. “I need to find Lily. Do you know where she is?”, he hissed.
Petunia looked as if she had smelled something very rotten. “Aren't you supposed to know that Severus? Aren't you one of her little freak friends?”, she scoffed. The young wizard held back the urge to curse her into next week and took a deep breath. He needed her help. She certainly wouldn't be very useful if she decided to hate him even more. Or if she could not talk anymore for that matter. Even though using his tongue sticking charm was very tempting right now. “No, Petunia, I'm sorry, but I lost the note with her address on it. The sooner you tell me, the sooner I leave.” The lie smoothly left his lips. He had always been good at lying.
This seemed to convince the older Evans sister. “I'll write you a note. Wait a second.”, she ordered and swiftly rushed back into the warm safety of her house, closing the door behind her. Severus could hear her hurried steps, as she rushed back along the entry hall. For a moment, he wondered if she would just let him stand there in the rain and not come back, or if she would decide to call her husband to chase him away. But both of those options would sooner or later lead to the neighbors noticing the strange man on the Dursley's property. And that was, of course, something that Petunia would never want.
So, after a few minutes that Severus had used to secretly change the color of Petunia's roses to black, the good old horse-face made her return. Oh, how Severus hated her. Had always hated her. She had always tried to keep Lily away from him. The black-haired man still felt so much malicious joy when he thought about the fact that Petunia had not been invited to Lily's and his secret blood-sibling ritual on the junk yard. Not that the older Evans sister would have ever approved to that. She despised dirt. Severus could almost see her disgusted expression in front of his mental eye when he thought about her finding out about what her sister and the “Snape boy” had done that day with a dirty, oily shard of glass.
The expression she wore now was probably very similar to it. With an absolutely hateful glint in her eyes, she shoved a crumpled piece of paper into Severus hand. “There you go, Lily's address. And now, stay away from my house. Stay away from this property. I never want to see you or any of your kind here ever again. Did I make myself clear? Good, because you freaks disgust me and I don't want any of you near my son. What if this magic humbug that you have is contagious? I wouldn't want my poor little Diddykins to become a freak like you!”
Again, Severus laughed. It was weird, really, that he had already done so twice this day. He hadn't laughed since Hogwarts, since the days he had still been friends with Lily. It sounded coarse and wrong from his throat. He shook his head again. “No Petunia, believe me, it's not contagious. If it was, your wish would have been fulfilled and you would have had it too. I mean, considering how much you stalked us when we were young...”, he mocked. With a huff, Petunia slammed the door shut once more. The bang echoed through the empty street.
Again, Severus stood alone in front of the Dursley house. The rain poured onto the concrete floor, just a few meters behind him, outside of the canopy. Through the slim windows in the door, the warm yellow light still shone outside. Carefully, Severus unfolded the sheet of paper and read Petunia's tight letters. The address was somewhere in Godric's Hollow.
Severus had already heard of the place. It was a small town with a surprisingly high magical population. Some said that even Godrick Gryffindor himself had once lived there. Added to that it was Dumbledore's old hometown. All in all, it sounded like exactly the kind of place James-damn-his-ass-Potter, of all people, would want to move to.
The former Slytherin already hated the town with a passion, and he hadn't even set a foot in it. He took a deep breath and reminded himself that this was to rescue Lily. He was the reason the Dark Lord was after her. He would warn her. It was for his always-sister, and that meant that it was worth it. Even if that meant walking straight into the lion's den and facing James Potter again. Thinking of that alone made Severus want to vomit off a cliff.
He couldn't suppress another sigh full of self-pity. Then he summoned the picture of Godric's Hollows town square that he had once seen in a book, back when he and Lily had made plans to travel the magical world, into his mind and disapperated with a crack.
