Okay here is one of my favorite parts in the series it's kinda my interpretation. The thought actually inspired the sequel… which will soon be up XD.

Locket-

"Please Luke!" he cried tears streaming heavily down his face. "Please drink some ambrosia! You can heal and live. Live with me!"

"Tempting," he joked. "But Percy not this time." He wheezed his own salty tears trickling down his face. He gripped Percy's hand and dropped a small box in it. "Don't open it until I am gone."

"No!" He cried. "You'll live I swear!"

"Shh-shh," he cooed cupping Percy's face in his hand.

Annabeth turned from the sight hiding her sobs as they racked her smaller frame. Grover tentatively rubbed her back calming the crying teenage girl.

"Percy, your eyes look like the misty storm we have gone through together." He kissed him groaning slightly at the still throbbing pain emitting from his injury. "I love you Persues Jackson. Don't forget me."

"I'll die without you! Please don't go!"

Sobs racked his body. Luke wiped the tears from his face. "Don't you dare give up. Live your life and keep going."

They kissed once again and when he relaxed back down he in haled and reflexively exhaled. His body stopped and his blue eyes lost their memorable mischivious glint.

Luke was gone.

"No! No! Gods why?" he cried shuddering and holding onto the body.

"Percy. He is gone." Grover whispered next to his friend pulling him off the body. "He died we need to go!"

Hours passed. Days slowly dragged on and the small box remained sealed and unopened.

Percy dragged himself out of bed and he looked at the dresser. In the middle of it was the small box dust all around it. He sighed and chipped off the wax opening the box. He pulled aside the single layer of tissue paper and found a note.

It read:

Don't give up and don't forget.
I love you
-Luke

A few tears escaped his eyes and he blinked back the rest and he looked at the small gift. It was a celestial bronze locket. Round and engraved.

On the outside it had the small engraving that was of a flying shoe and trident placed over the middle of it. Inside was a picture Annabeth took when Luke was teaching him archery.

"I'll see you again…"

FIN.
