Luke was debating whether or not to skewer Percy's head while fighting a pack of hellhounds. 

Where in the name of Chaos was Percy?

He jumped over the rabid looking creatures from hell and aimed his sword at a cyclops' eye. The cyclops stumbled back, holding his injured eye, stepping on his allies while doing so. Luke turned and spotted Zoe shooting arrows at insane speeds at the enemies around her. Beads of sweat were pasted against her forehead. Her eyes were full of determination and focus. Her dark hair was held in a braid with a few a strands framing her beautiful face. Her mouth opening and closing as if saying--

"Idiot!" An arrows shot past Luke and nailed a hellhound, that was about to pounce on him, on the forehead, instantly killing him. "Stop daydreaming while were engaged in battle. Are you trying to get yourself killed?" She shook her head in exasperation and left Luke with 3 remaining hellhounds.

Luke lowered his head in failure. Why was Zoe so...Why did he feel strange when he was around her?

(Face it, Luke was as dense as Percy when it came to love. Really, after having fangirls, you'd think he'd know a thing or two about love...)

He shook himself out of his daze and looked at the hellhounds. He imagined them saying: "Yeah, it's okay, buddy. We know how you feel." Though it was hard to picture it when the wolves stared you down with a predatory gleam in their eyes that make them look as if they're trying to tell you: "Hey, buddy, how do you feel about bathing in barbeque sauce? Of course, the sauce will work if it's your blood!"

...And this is when you find out that long exposures to Percy will lead to strange thoughts.

Luke stopped his line of thoughts and observed the surrounding area. Annabeth was fighting a few evil harpies (They probably turned evil because they couldn't find their 'Tyson to their Ella') with several dead campers around her.

Luke grit is teeth. If they hadn't interfered they still would've been alive...

That was when he was hit by a cold sense of dread. He only got this feeling when--

He turned around and spotted a knife aimed for his heart. He felt himself freeze. What...What was happening? Why was he freezing like this? Why couldn't he move?

A black blur intercepted the arrow.

And blood was spilled.

o.0.o

He could see nothing.

His vision was getting dark.

Everything was fading.

Everything was slipping from the his grasp.

He gave up Elysium,

It was a second chance.

He would die tonight,

He knew without a doubt.

He could hear their distant voices.

His friends who stayed by his side.

He'd die without regrets,

Because...

He saved his best friend.

o.0.o

Luke could hear his heart banging against his rib cage. 

Thud...Thud...Thud

"No..." His voice exuded pain  and suffering and self-loathing. 

This was all his fault...

His chest ached; His throat burned.

Luke once again realized how weak and pathetic he was. It didn't matter if he was given a second chance. It didn't matter if he tried his hardest to suppress his guilt. It didn't matter his hard he tried to grow stronger to protect his friends because in the end...

They'd all die again...wouldn't they?

He could feel tears cascading down his face in little rivers. He could feel the dark atmosphere that surrounded him when he was with Kronos. He could feel the guilt chewing him up.

His friends didn't deserve to die. Luke did.

All his life, he did nothing but hurt the people around him--the people who would willingly give up their life for him.

He clutched the fabric of his best friend's shirt tightly and let the tears fall. He shouted at the heavens; He didn't care. He screamed his throat raw. Let the world know of his pain, he didn't care. The pain was too immense to keep bottled up. He cursed fate.

It was a lost cause but Luke didn't want to believe it. His chest was heaving in an effort to stop the tears. "I'm sorry...I'm sorry..." He kept repeating those two words when clearly they couldn't make a difference.

His eyes widened when he saw his hand wrap around his. 

He smiled. "It was my choice..."

Luke couldn't say anything as he stared at the knife still embedded in his stomach. Blood was seeping through his cloak. He was in great pain but still...

He smiled. "The greatest heroes die with smiles, don't they?" 

He  smiled yet Luke could not bring himself to do the same as he saw the light fade out of his  eyes
