Leo sat in his room, facing the wall. 'why am I so mad? Nico didn't say more than I already knew... so what is it' he thought as he fiddled with the parts in his hand, tinkering with the things from his tool belt gave him some way to get rid of the stress he felt, but it was still not enough.

"You just bottle up the way you feel... waiting for it to explode like one of your machines."

That's what Nico said was his fatal flaw, and Leo just couldn't get over that line. It repeated in his head every time there was silence. The sad thing was, Leo knew Nico was right.

'What can I do about it anyway? I don't want to worry them... they already have enough stress just getting over everything from Greece, and... my leaving them.' Leo cringed as he remembered what happened.

"Calypso? Calypso? Where are you?" Leo yelled as he looked for her in the busy streets of Chicago.

They were on the Navy Pier, doing some sight seeing. Leo offered to pick up some classic American style Coney dogs, but when he returned he couldn't find her. 'weird' he thought, he tried checking the surrounding area, but when she still didn't show up he started to grow scared. 'What if some monster took her? what if she was kidnapped?' then his worst fears came to mind 'what if she left me?', that caused Leo to stop in his tracks. Leo continued walking, his pace growing faster, then as if by chance he found her; She was in the arms of a Buff man, maybe 35, with a crew cut and overly tanned skin.

"Calypso? What's going on?" Leo asked, confused at the sight.

Calypso wore a smirk on her beautiful face, "Oh Leo, poor poor scrawny Leo, did you really think I loved you?"

"Calypso, you're? No! You don't mean that!" Leo shouted in a frantic tone.

"Babe, do you need me to take care of this little shit?" the man holding Calypso asked.

Calypso wiggled out of his arms then walked up to Leo, "I just needed to free ticket off that Island, and who better to do it then one Hero who was naive and lonely, but more importantly, on a quest to save the gods? I knew you would get something out of the deal."

The evil in her eyes sent a chill down Leo's spine, 'that can't be her' he thought, "There's no way, prove it, prove you're Calypso right now! The Calypso I know would never do this!"

The hope in Leo's eyes vanished when she started to sing, it was the lullaby she sang to him on some nights, tears formed in his eyes, he treasured the tune that so long ago had bewitched him.

Calypso stopped singing, "I've used that same tune to enchant many men. Is that proof enough?"

Leo's tears finally fell, "why? Why did you do this?"

Calypso leaned forward and in his ear whispered, "Maybe if you had studied greek better you would know this, my name means 'to deceive' Leo. It's in my nature, and I had a goal. It's nothing personal, you just fit the bill."

Leo stopped the memory, it hurt too much. He noticed voices outside his door, they were Jason and Piper's, so he got up to check it out.

"Piper, lets just leave him alone, it's for the best..." Jason's voice said reassuringly to Piper he assumed.

"But, Jason, what if..." Piper continued in a whisper, "what if he leaves again?"

Leo cringed, 'why did they have to talk about that again?'

"don't say that Pipes... he won't do that to us again..."

"how do you know Jason? I'm sure we wouldn't have thought that before when he did it the first time! He just up and left us for a crush only to have her dump him for some stupid-"

Piper's words hurt to much, Leo couldn't take it and took that moment to pop out of the room,

"If you two wouldn't mind, can you discuss my mistakes somewhere else, I don't feel like meeting the ghosts of Christmas Past right now!" and with that, Leo slammed the door, going back to his bed to wallow in his own misery at his mistake.
