Firstly, thanks for the reviews and support! It means a lot to me!

Second/final chapter :) Hope you enjoy!

(Disclaimer: I did my best not to actually talk about the things that happened in the actual books, because some of my moments happened in them. So yeah, I take no claim to the events of this story - just Luke's thoughts, really)

Set in The Battle of the Labyrinth

"Please," Luke says, and there is true desperation in his voice. "We could go right now, and get away from all of it."

Annabeth's guarded look never hurt him more. "No, Luke. How am I supposed to know if I should believe you or not?"

They're standing on two sides of the door - Annabeth within the "safety" of her house, and Luke outside on the porch. Two sides of the door. Olympus and Kronos.

"You have to," Luke pleads. "I can't tell you why. But…the time's coming soon, and I don't have much time left."

"I can't." Annabeth is shaking her head, trying to block him out. "I have a duty to keep to Camp Half-Blood. To Percy. Unlike you, I'm not a traitor." Her grey eyes flash dangerously.

Funnily enough, it's not the last line that makes Luke frustrated; it's the part about Percy.

"Percy has a lot of people following him," he says with bitterness. "You don't need to be one of them."

Annabeth flares up. "Did you come here to try to bring me to Kronos's side? Because if you did, I swear, you don't know me at all!"

Luke shakes his head. "No! Annabeth, that's not what I meant. I told you. I want you to run away with me."

She glares at him suspiciously, and it breaks his heart. Somehow, this girl seems to be doing that lately. "I don't believe you." But there's a hint of uncertainty in her voice.

He hangs onto that uncertainty. "Look, I know I've betrayed you and Thalia. I'm sorry. Please believe me when I say that I want to run away. Family. Remember?"

Annabeth's eyes glance down to the Celestial bronze dagger hanging by her side. When she looks back up at him, her face is expressionless, but he notices that her hands are gently caressing the blade. "Family," Annabeth repeats softly. "You know, Luke, Thalia and I weren't the ones who broke that promise. You did."

She shakes her head, and her words become steely and guarded again. "I don't believe you. Go away, and don't come back." Annabeth swiftly turns away, and, as a daughter of Athena wisely would, slams the door in Luke's face and doesn't look back.

Luke wants to call her back, and plead with her - he wants to scream her name, tell her what's going on, and keep begging her to go with him. But he knows she won't turn back.

So instead, he slumps down to the wood floor of the porch, holding onto the railing above him, and whispers to the stupid door, "I'm sorry, Annabeth."

(He notices he doesn't say the Unspeakable. Maybe it's because he can't, but maybe it's because he's scared.)

Luke is drifting. He thinks he's about to drown, and he's okay with that, because he's not quite sure he has the strength to stay alive.

Except, what did that man - Achilles - say? Oh. That he had to think of something to keep him strung to shore.

Luke's eyes are already closed, but he squeezes them shut even more. There's nothing to think about, other than Kronos and how he wants to take over his body. What else? Think about that god of a father? He'd rather die than have that traitor be his lifeline.

Luke attempts a wry grin. It's kind of hard, because the flowing River Styx is pretty much killing him by the second. But he finds it funny that he really can't think of anything worth living for.

Somehow, he can't find his situation serious. In fact, Luke knows that if the pain wasn't so shockingly real, if the river wasn't deteriorating his body, he'd be outright laughing. It would be real, too. The laughing would be real, just like when he was with-

A picture of Thalia and Annabeth explodes into his mind, temporarily blocking the pain. Luke violently tries to shake his head - he doesn't want their involvement in this, he doesn't want them to see this happen to him. He tries to lift his fingers to his head to make the image disappear.

But, for one, he physically can't move his fingers. And besides that, the image only brightens and becomes clearer.

He sees Thalia beckoning him to shore, Aegis held like a raft in front of her. She's shouting to him, and he thinks it's words of encouragement (he can't hear her), because she's smiling.

And Annabeth. She's smiling, too. Her smile is sweet and lovely, and her blonde curls stand out in the darkness of the Underworld. Seeing her in comparison to Hades's realm makes his heart hurt - how can something so innocent and beautiful be somewhere so dark? But the strangest thing about Annabeth is that he can hear her.

"Come on, Luke!" she says, grinning ear to ear just as she had back then. "I know you can do it. Just keep thinking."

Luke tries to tell her that it's hopeless, but he can't speak. Even so, Annabeth shakes her head like she knows what he's thinking.

"Keep thinking about us, Luke!"

She's holding something in her hands, and it takes Luke a while to see that it's a string, and that it's connected to his underarm.

Luke knows a sign when he sees one, and so he lets Annabeth and Thalia pull him to shore. He lets Thalia lift him up out of the water on Aegis, and he lets them place him gently onto the rocky ground. He allows Thalia to stroke his hair, and he welcomes Annabeth to hold his hand soothingly.

But when he comes to reality, he doesn't allow them to leave, even though they were never there in the first place.

Luke sits in the stands, watching Antaeus and the stupid centaur fight, when that Percy Jackson walks in.

He hates Percy Jackson and his blind arrogance.

But Luke realizes just how much he hates Percy Jackson when he sees Annabeth screaming at him, dracaenae holding her back. He's stunned to see her, of course. He's stunned to realize that he's happy to see her.

And then, before Luke can even process Annabeth's presence, that Percy Jackson battles Ethan Nakamura, and spares his life. And then Jackson goes on to defeat Antaeus and escape, taking Luke's everything with him.

"Stop." His voice is deadly silent as he addresses the room of babbling monsters. They all shut up, naturally. "I want each and every one of you out!"

He wants to scream, but he thinks he might start falling apart if he does - oh, wait. He forgot. With the power of the River Styx, there's practically no way he can fall apart.

The disgusting beasts are out of the arena in less than ten seconds. Luke is left in the vast room by himself.

He should feel angry. Livid. He should feel like killing everything around him.

Instead, he feels pain. Agony. He feels like his heart has been ripped out of his chest.

That Percy Jackson. Working under the gods' favor, working and manipulating people to work with him. And if that weren't enough, working and manipulating Annabeth.

"Why?" Luke murmurs to the sand in the room. "Why would you risk your life like that, for him?" He spits out the last word with venom. He glances down at his hands, and says, even more quietly, "Why for him and not me?"

He kicks up sand from the ground, and clenches his fists. He has to get a grip on himself. Every time he thinks of Annabeth, it's one more chance that Kronos will see what his biggest weakness is (other than his Achilles' heel).

Annabeth, he thinks to himself sadly, if only we were on the same side.

Set in The Last Olympian

Luke isn't Luke anymore. When he moves, it's not really him moving. And when he thinks, it's not his thoughts. It's Kronos's.

Kronos laughs. That Percy Jackson. Fighting bravely and pathetically on the Williamsburg Bridge. Kronos was obviously in power, and yet the boy had the nerve to destroy some of his army.

Except… Kronos isn't sure that he's completely in power. When he saw Ethan Nakamura (a fairly worthless half-blood) nearly stab Jackson, but stabbed the girl saving Jackson instead… something in his conscious wasn't his. He wasn't in complete control.

Kronos knows it was the boy - the Luke Castellan, his body host. But it wasn't until that moment where Kronos knew that the Castellan boy had a weakness he wisely did not reveal beforehand.

Kronos lets out an condescending laugh. Strange, how love works, and yet even his soldiers fall to it.

It's pathetic. It allows weakness.

Luke is himself, and he's dying. He knows he's himself, because he's just stabbed himself bloody. He knows he's dying because he can't feel a thing, even though he's just stabbed his Achilles' heel.

He's slipping out of consciousness, but he knows he needs to focus. He needs to tell her.

Annabeth. She just saved the world, and she just saved his soul. She's limping to him now, even though she's hurt. Because of him. She's hurt because of him.

She reaches him and takes his bloody hand. He wants to apologize, but he knows he can't waste his words.

Her eyes are filling up with tears, as she shakes her head. Her body heat is warm and comforting. Even though she's covered in grime and blood, Luke is sure she's the most beautiful person on earth and Olympus combined.

He tells her stuff about family, about him, about her. She nods, and then, he knows it's time.

The words are already forming on his lips, but he swipes them away. He can't. So instead, he asks a different question, and when she and Percy Jackson exchange a long look, Luke knows it's hopeless. He wishes he'd seen what a miracle he'd had right in front of him when he'd had the chance to. But it's too late now. His soul might have been saved by the girl he loves, but his heart was crushed by her, too.

Luke turns from her. He can't look at her angelic face anymore. He can't look at her tears, which are for his mistakes. He can't see the pain etched onto her face.

Luke finishes his talk with Percy Jackson, and he knows he's going to die, and suddenly, he's abnormally panicked, and he looks into Annabeth's eyes, and he's about to say it, he swears he's about to say it, and his mouth is trying to form the words-

And then he dies, so Annabeth doesn't know and will never know that he wanted to say the Unspeakable.

("I love you, Annabeth Chase.")

I'd love any kind of feedback from y'all, about this :) Thank you!
