Author's Note; Well, this was not my favourite thing to write, I'll tell you that. I love the book version, and the movie version, so I kind of mixed the two up. All the same, my knowledge of both is a little rusty, so it may not be completely accurate. Enjoy!

"Who's the Half-Blood Prince?"

"Who?"

"That's what is says. 'This book is property of the Half-Blood Prince.'"

"I dunno," Harry said. He was looking at the book, but Ginerva 'Ginny' Weasley was staring at Harry. As were Lily and James, as always.

"Ah…young love," James said, stretching out in a chair. Of course, no one else could see him except Lily. "I remember sixth year romaaance," he drawled out.

"Yes, you chasing me all around Hogwarts and never giving Remus and…" Lily trailed off, her eyes dark. "…Well, never letting him have a break."

"All love, Lily dear." James replied.

"But all the same…" Lily said. "What are the odds that Harry got Severus' old book?"

"Snivellus is the Half-Blood Prince?" James said incredulously.

"Yeah. I remember his book. Filled with notes in the margins.. I always told him that he should just write on parchment, but he never paid attention." She said fondly.

"When did you two stop talking?"

Lily sighed. "I don't even know. When he started hanging out with the first Death Eaters, really. Then…he called me a mudblood."

"I remember." Or, more particularly, he remembered the detention he'd served in the Forbidden Forest after he pushed Snape into the lake.

"I don't know what happened to him… he just changed…"

It seemed as if Harry and Dumbledore had been gone forever. Of course, once they had Apparated away, Lily and James had lost them. After a frenzied search, they returned to the castle, floating in the air and watching the grounds.

"Where could they have gone?" Lily asked fearfully. They had heard screams from inside the castle. It seemed that Death Eaters had infiltrated the building. The teachers were holding their own, but the students were all in danger.

"I don't know, Lils. At least Harry is safe with Dumbledore…"

As soon as James spoke, the familiar whoosh of a broom cutting through the air sounded. Lily and James turned in harmony to see a broom with two on it ride through to the castle.

"Harry!"

"And Dumbledore…why didn't they just Apparate?" Lily asked.

"I have no way of knowing. But we need to warn someone," James said, taking off.

It took a while to find McGonagall and 'lead' her in the right direction: the Astronomy Tower. Lily and James hurried up to the top…and froze.

Draco Malfoy was backed by three Death Eaters, his wand pointed at Dumbledore. Harry was nowhere to be seen.

"What is he doing!" hissed Lily. "Why isn't he stopping Draco!" He, meaning Snape.

James knew all too well what Snape was doing. "Lily, find Harry." When he tried to argue, he yelled, "GO!" and she took off. There was silence for a long moment, and then Snape pushed Draco out of the way, taking out his own wand…

"James, I found him, he's under the Cloak, he's right down…" Lily said, but the blood drained from her face.

Because with two words, Snape had just single-handedly killed Albus Dumbledore.
