The snake struck the man against the wall fast, draining whatever life was left in him swiftly. Rosalyn winced with every strike, covering her ears. She couldn't stand this.

Finally, (probably when Voldemort decided Snape had enough poison in him that he would surely die in a minute) Voldemort and Nagini left.

Rosalyn didn't hesitate. She had hated Snape her whole life knowing him, but it just be didn't seem right to leave him lying there. It didn't seem right that the last voice he would hear would be Voldemort's.

She ran inside the boathouse and Harry, Ron and Hermione soon followed her.

Rosalyn immediately saw Snape, lying on the floor, blood pouring out of him.

She knelt beside him and he looked straight into her eyes. Neither talked.

Suddenly, Snape began to cry. Rosalyn didn't blame him, but she was confused when he started to talk. "T-take them. Take them. P-please."

Rosalyn didn't know what he was referring to but as he used his last remaining energy to point to the tears running down his face, it wasn't that hard to figure out.

"Give me something!" Rosalyn yelled to the three people behind her. "Quickly, a flask, anything!"

Hermione quickly supplied her with a flask and Rosalyn held it to Snape's face, making sure the tears ran into it.

"Take them... to the pensive," Snape said in a low voice as Harry came and sat beside Rosalyn.

"Look at me," Snape ordered them.

There was a pause in which the grey eyes looked not at hazel, but at bright, emerald green. Snape stared at Harry. "You have your mother's eyes."

Harry nodded numbly as Snape turned to Rosalyn. "You look just like her, like Lily."

Rosalyn's eyes pooled. For a second, Snape struggled against death, trying to stop the inevitable, then, with his last words said, he lay still. His eyes went dark.

His last word had been 'Lily'.

Rosalyn stood up, numbed by the pain Snape's death had given her. Suddenly, a hiss came sweeping through the boathouse. Rosalyn was sure that the whole castle could hear it as well.

As Lord Voldemort spoke again.

"You have fought valiantly... but in vain. I do not wish this... every drop of magical blood spilt is a terrible waste... I therefore command my forces to retreat. In your absence, dispose of your dead with dignity..."

Rosalyn braced herself as her name came up.

"Rosalyn Potter, I now speak directly to you. On this night, you have allowed your friends to die for me rather than face me yourself... There is no greater dishonour. Join me in the Forbidden Forest and confront your fate... if you do not do this, I will kill every man, woman and child, who tries to conceal you... from me."

Rosalyn digested this as she, Hermione, Harry and Ron ran up the hill back to the castle. Voldemort was trying to make her guilty, so that she'd go to the forest. She couldn't. She just couldn't. The snake still needed to be killed.

"Where is everybody?" Hermione asked as they walked through the empty courtyard.

The action, it appeared, was going on in the great hall. Rosalyn looked around and saw dead everywhere, and people treating to them.

She saw Lavender Brown... Colin Creevey... Tonks and Lupin... and-

With a thud in her heart that was even worse than when she saw Lupin and Tonks, she saw Fred, lying on the ground, dead. She saw all the Weasley's around him, sobbing.

And that's my fault, Rosalyn thought hopelessly.

She also saw Augusta Longbottom. She wasn't dead, but she was weak, and, as Rosalyn heard people talk, she soon knew that it had been the cruciatus curse.

I did that. Will Neville even love me anymore?

Rosalyn couldn't take much more. Soon, she left the great hall, and sat on what was left of the grand staircase. There, she put her head in her hands and sobbed.

Her body shook and she coughed and spluttered, but she kept crying.

Tears... what was I supposed to- the pensive! Rosalyn suddenly thought.

Drying her eyes on the edge of he shirt, she stood up. She ran up the stairs, trying to remember where Dumbledore's (as she would always call it) office was.

Finally, she managed to find it. The corridor in which it was in was in alright condition, and Rosalyn got there fairly easily. The door was destroyed, so no password was needed, but the office was fine.

Rosalyn immediately went to the cabinet in which she knew the pensive to be in. When it opened, she saw the stone basin, and immediately, she put the tears in the basin.

Then fell headfirst into it.

She was suddenly on a hill side, where two girls, one a red head, one a brunette, were playing. When Rosalyn got closer, she saw the red head had a wilted daisy in her hand. In a second, however, she made it grow into a full bloomed one again.

"Freak!" The brunette shoved the flower out of the red head's hand and she started to run away up the hill. "I'm gonna tell mummy! You're a freak, Lily, a freak!"

For Rosalyn, everything became clear. This was Petunia, the woman that, now, never spoke of her sister, and pretended that she had never lived. The red head was Lily. Rosalyn's mother who she looked so like.

Suddenly, a boy came out from behind a tree, making Petunia run away. This boy was taller than both the girls, though no doubt the same age as them, and he had black, slightly greasy hair.

This was Snape.

He picked up a bit of grass from the ground and made it fly over to Lily, who caught it. She realised that he could do it too.

The scene switched, and Lily and Snape were lying beside a lake, talking.

"She's jealous, because she's ordinary, and you're special," Snape was saying.

"That's mean, Severus," Lily said kindly.

The scene switched again, and Lily had the sorting hat on. "GRIFFINDOR!"

Snape watched as she went and sat down, and shook hands with a boy that had the same set of eyes that Rosalyn was staring at him with...

"Hi, I'm James," he said, shaking his future-wife's hand.

"Lily."

"And I'm Sirius," the messy haired boy in her other side introduced himself.

"Izzy," said the smiling red head, who had been sitting next to Sirius.

"I'm Alice," a girl opposite Lily introduced, and Rosalyn found herself staring into her boyfriend's eyes when she looked at her.

Then Rosalyn turned round to see Snape glaring at them. Soon he was sorted into Slytherin, and Lily was about to see how different they really were...

The scene suddenly changed, and James and Sirius were running through the corridor, pushing past Lily who was carrying a load of books, and knocking them to the ground. Snape helped Lily pick up the books, he was there for her from the start...

Suddenly Snape was older, and with Dumbledore on a hill a couple miles away from Hogwarts.

"Don't kill me!" Snape begged.

"The prophecy did not refer to a woman," Dumbledore told him. "It spoke of a child born at the end of July-"

"Yes but it's her children!" Snape said, crying now. "He thinks it's one of her children! He intends to hunt her down and kill them! Hide her. Hide them all. I beg you."

"And what will you give me in exchange, Severus?" Dumbledore walked forward.

"Anything," Severus said without hesitation.

Change of scene again. Rosalyn and Harry were in the crib, Lily was knelt beside it, whispering to her children. "Harry, Rosie, you are so loved... momma loves you... dadda loves you... so loved... Harry, Rosie be safe... be strong..."

And when Voldemort came, he killed her. Lily screamed as she fell, dead, to the floor.

The scene changed yet again... Snape was in Dumbledore's office, and Dumbledore was surely there too...

"You said-" Snape choked on his words. "You said you would keep her safe."

Dumbledore, who was staring out the window, turned round. "Lily and James put their faith in the wrong person, Severus, rather like you." He started to walk towards Snape. "The girl and boy survived."

"They don't need protection, the Dark Lord is gone!" Snape burst out.

"The Dark Lord will return," Dumbledore said gravely. "And when he does, Harry and Rosalyn will be in great danger.

"He has her eyes," Dumbledore reminded Snape. "And Rosalyn looks just like her. So, Severus, if you truly loved her..."

Snape's head jumped up. "No one... can know."

"That I should reveal the best of you, Severus?" Dumbledore looked straight at him, and Snape could no longer hold his gaze.

The scene went to Rosalyn getting sorted.

"When you risk your life every day to protect them..."

Then it changed again... Dumbledore's hand was black, shriveled and not looking very good.

"I have contained the curse to your hand for the time being," Snape said. "But it will spread, Albus."

"How long do I have?" Dumbledore asked.

"Maybe a year," Snape guessed, then he made to walk away.

"Don't ignore me, Severus," Dumbledore said boredly. "We both know Lord Voldemort has ordered the Malfoy boy to murder me. But should he fail, one should presume the Dark Lord will turn to you."

There was a pause in which the things unsaid hung in the air. "You must be the one to kill me, Severus," Dumbledore said. Rosalyn gasped. "Only then will the Dark Lord trust you completely."

Snape on the tower- he killed Dumbledore- Rosalyn, looking furious-

And then the final scene.

"There will come a time when Rosalyn Potter must be told something," Dumbledore and Snape were in the office again, Dumbledore talking urgently. "But you must wait, until Voldemort is at his most vulnerable."

"Must be told what?" Snape asked.

Dumbledore sighed. Rosalyn knew she was about to learn the truth.

"On the night that Voldemort went to Godric's Hollow to kill Harry and Rosalyn... and Lily Potter cast herself between them... the curse rebounded.

"But not before Rosalyn Potter could stick out her hand to protect her brother.

"And from there, a part of Lord Voldemort's soul latched itself onto the only living thing it could find. Rosalyn herself."

Rosalyn gasped.

"There's a reason Rosalyn can speak with snakes, there's a reason she can see into Lord Voldemort's mind, and there's a reason her scar is on her forearm. A part of Voldemort lives inside her."

Snape paused. "So, when the time comes... the girl must die?"

"Yes, she must die, and Voldemort himself must do it, that part is essential." Dumbledore said slowly.

Snape realised. "You've kept her alive so she can die at the proper moment... you've been raising her like a pig for slaughter."

"Don't tell me now, that you've come to care for the girl?" Dumbledore almost teased.

"For her?" Snape exclaimed. "Expecto patronum!"

From his wand burst the silver doe. Rosalyn finally understood that as well...

"Lily?" Dumbledore looked up at the doe. "After all this time?"

Snape's dead eyes looked straight at him. "Always."

Rosalyn suddenly felt herself shooting up. She finally had the truth.
