Author's note: This is my first ever fanfiction. I know it's not well written and I would appreciate constructive criticism. Snape is kind of OOC in this but only towards Harry. He's still the sarcastic Snape to everyone else. So, please review this. It would mean the world to me.

Snape stood in an empty field. He was alone, wandering around.
"Sev?" a voice behind him said quietly.
Snape whirled around, finding a pair of gorgeous green eyes looking at him. The same pair of eyes he had missed for seven years.
" Lily! Is it really you?" Snape asked, voice shaking. She started to walk towards him, grinning.
"Yes Sev, it's me. Did you miss me?" Lily asked while pulling him into a hug.
" Of course I've missed you Lily! I can't believe it's really you..." He started to break down in tears. "It's all my fault! I practically killed you. I should be dead instead of you. Your son..."
"Oh Sevvy, it's not your fault. Don't ever think that. We died to protect Harry." She pulled away from him and looked him in the eyes. Snape could barely look at those green eyes. It hurt too much.
"That's actually why I'm here. Harry needs someone to love and care for him. He needs you Sev."
"Hmmph, he's living with your lovely sister." Snape sneered" He doesn't need the man who caused his parents' death."
"Sev! Stop saying that! It's not your fault. And Harry does need you. They're abusing him Sev. I can't take it. My own sister..." Lily started to look lost and her eyes filled with tears.
"Lily? What do you want me to do? They're his legal guardians "
"Please. Please just visit him. Tell him what happened to us. Show him- show him that there are people who love and care for him."
"But... But he's Potter's son. How can I possibly..." Snape was at a loss for words. How could Lily expect him to care for that arrogant Potter's spawn? After all the trouble and pain he caused him. And as soon as he thought that, James Potter himself began to materialise right in front of him.
"Severus, I'm so sorry. I was a complete prat to you in school. But please don't take it out on my son."
Snape just stared at the man who made his life hell. Lily hugged him tightly again and tears began to trail down Snape's cheeks.
"Please Snape. Do it for me." Lily whispered.
"I-I promise. I will." Snape said sighing deeply.
She pulled away and began to walk in the opposite direction with James at her side.
"But where are they staying?" Snape shouted after Lily and James who started to fade.
"Number four, Privet Drive, Little Whinging, Surrey..." Lily said, her voice distant "Please help him Sev..."
And then they were gone.
Snape paced around his room, arms folded tightly to his chest, thinking about the wild dream he just had. His dream had confused him even though it was obvious what he was supposed to do. The thing was, should he do it?
Well, of course you should! He's Lily's son! She said he needed you. They're abusing him! The voice in his head sounded exasperated.
Were they really abusing him? Petunia was never the nicest person but could she really be capable of child abuse? Snape sighed and slumped down into a chair. He had to check on Harry. He had to do it for Lily.

Snape stood in front of Number four Privet Drive, arms folded. He tugged at his muggle clothes. Dear Merlin, those clothes were bloody uncomfortable.
Just as he knocked on the door, he heard the sound of running water and tuneless humming. He was about to walk in the direction of the noise when he heard loud thundering
footsteps walking towards the door. The door opened and a rather round boy who looked to be around seven glared at Snape. Snape, of course, glared back.
"Who're you and whadduya want?" the boy asked, mouth full of food. Snape looked disgusted and rolled his eyes.
"Learn some manners you dunderhead" Snape said icily " I wish to speak with Petunia Dursley and Harry Potter."
The round boy just turned around and shouted " MUM! SOMEONE'S AT THE DOOR FOR YOU!"
Snape resisted the urge to smack the back of the boy's head. He waited in the doorway with his arms folded.
"Duddykins, if it's those sales people again, tell them we don't want to- YOU!" Petunia Dursley saw Snape and recognised him immediately.
"Get out! Get out of my house you filthy freak! And don't you dare set foot in this house ever again!"
"Oh Petunia, it's nice to see you too." Snape replied dripping with sarcasm. "Sadly, I'm not here to catch up with you. Where is Harry?"
"Did you hear me? GET OUT!"
Snape tutted. "Now now, Tuney, you don't want me to get angry do you? I won't be responsible for any accidents" Snape's gaze flickered to Dudley who was staring in shock. Petunia looked terrified and ran in front of Dudley.
"Don't you dare hurt my Duddykins!"
"I won't if you let me speak to Harry. Now, where is he?"
"You're lucky Vernon isn't here. He'd beat you to a pulp."
"I'd like to see him try." He sneered. "Now, where is Harry? I don't like having to repeat myself, Tuney."
"H-he's outside in the garden. I'll get the boy. Dudley, go to your room and stay there! Do not come down."
Dudley practically ran up the stairs, obviously terrified of Snape who glared at him. Petunia walked into the kitchen and went out the back door.
Snape, still standing in the doorway heard the water hose outside stop and something that sounded awfully like a slap.
"I'm sorry! I didn't mean to overwater the flowers! I swear!" a scared voice said.
"Just come here you stupid boy! There's someone here to see you. He knew your freak of a mother."
Snape's jaw tensed at her words. She still hated Lily even though she was dead. Disgusting woman.
The back door opened and Petunia walked through, pulling the ear of the skinniest child Severus had ever took one step in and Petunia shrieked.
"Stay out! I don't want filth in here."
"Oh but Tuney, I was so hoping we could have a nice little chat over tea." Snape smirked at her angry yet scared expression.
"The boy's not allowed to eat before seven." She gave Harry a shake and he let out a small whimper, staring down at the floor. Snape could tell what Lily meant when she said he was abused. Just by looking at him you could tell that he was severely underweight and he had bruises all over his arms. He was wearing an old shirt that looked like it was meant for someone more than twice his size.
"No? Well, maybe I could take him out for tea. I have a lot to discuss with him. If that is okay with Harry of course." Snape had spoken in his usual drawl but inside he was nervous. He had promised Lily he would care for him but what if the boy didn't want his care? He knew how abused boys minds worked. They build a wall around themselves and will do as much as they can to prevent it from coming down.
Petunia just stared, confusion spreading on her face.
"Why are you doing this? You and Lily weren't talking to each other when she died. Why do you care what happens to him?" Harry flinched at his mother's name and Snape sighed.
"I promised her. That's all I can say. "He took a deep breath." Harry would you like to come to this nice café near here? There are some things I would like to talk to you about."
He nodded his head slightly then said quietly "You knew my mum?"
"Yes, Harry, I knew her since we were kids. Do you want to know about her? I can tell you once we get to the café."
Slowly, Harry nodded his head. Petunia hit the back of his head causing another whimper to escape his lips.
"You are not going with this freak." she hissed "Go to your cupboard now."
Snape was furious. How dare she treat a child like a dog?
"I didn't want to do this Petunia but you leave me no choice." Snape's right hand reached into his left sleeve and pulled his wand out. Petunia shrieked at the sight of his wand. Harry who was still staring at the floor seemed to think her shriek was the start of a violent outburst and fell to the ground, clutching his legs and shaking.
Merlin, this boy must be really traumatised.
" Go! I'll take care of the boy since you're obviously incapable of doing so. I shall bring him out and tell him everything you refuse to. I'll bring him back later and Vernon better be here as well." Snape hissed, voice full of loathing.
After Petunia ran upstairs to her 'Duddykins', Snape went over to Harry who was still shaking on the floor and crying.
"Aunt Petunia, I'm so sorry! I'm so useless. Please don't hit me." Harry pleaded." Harry, don't worry. My name is Professor Severus Snape. I will not hurt you and neither will your aunt. Not anymore." Snape whispered soothingly while rubbing his back.
Harry stopped whimpering and shaking. His breathing seemed to slow down but his face flushed with embarrassment.

"I-I'm sorry Mr Snape. I didn't mean to cry."
"It's quite understandable Harry. Your aunt is a horrible woman." This got a weak laugh from Harry.
"Harry, how about we go to that café and I tell you all about your mother?"
"Bu-but Aunt Petunia said I couldn't. "
Snape sneered."Don't you worry about your aunt. We shall go now if that is okay with you?" Harry nodded and started to get up.
He breathed a sigh of relief. So far, things seemed to be going well despite Harry's breakdown. He stood up and took Harry's tiny hand in his causing Harry to finally look up at him. Snape felt the wind knocked out of him. His eyes... He really did have Lily's eyes.
