Leo Dies at the End

Leo thought about everything that went wrong for the past week.

Annabeth had killed Taylor, and she also has amnesia.
Taylor is dead.
The Argo II was destroyed.
And two women showed up, claiming to have been spying on them.
What a week.

The fountain of youth, as Dante had described after the monster attack, was a fountain that... Well, granted youth. Dante believes that the "fountain guardian" that *guess what* guards the fountain will grant a wish if you "return what is rightfully hers."
Thanks to the Oracle girl, they had an idea where the fountain might be located... southwest. But she had also said that we should stay put. So, it was split half and half.
Percy, Annabeth, Hazel and Frank were staying behind at the hut, while Dante, Leo, Medea, Andra, Piper and Taylor's corpse were going to find the fountain.
"Are you guys sure you'll be alright?" Dante asked Frank, who was the second to only sane person staying at the hut.
"We'll be fine." He said, pulling Hazel into a hug. They kissed, and left for the hut. Percy was still in complete shut-down mode, devastated about Annabeth.
"Everyone ready?" Andra said, looking around. "And where is that hair brush?"
They all agreed, and started to head South West.

Besides a few monster attacks, the trip wasn't that bad. The worst part was when Piper got eaten by a monster, who- after being freed from the monsters stomach- complained about the smell the rest of the time.

When they reached the far side of the island, there was... a casino?
"How did we possibly miss this?" Leo muttered, looking at the building.
They walked up to the entrance of the Casino, but Dante stopped them from going any further.
"We should leave our stuff out here." He said. "Only bring in the stuff we need, like weapons."
They all nodded in agreement, and put all of their stuff behind a log.

They headed inside the casino and proceeded to look around. There were a ton of things that didn't belong; Toilets, bathtubs, sinks, a hippo, but no people.
That is, until a robed figure walked down the stairs.

"Greetings, heroes. I've been expecting you." She motioned to a table. "Sit."
They all were a bit hesitant, but Sat down.
She looked around at her guests, but her eyes landed on Leo, and after moment, pointed a bony finger at him.

"You were suppose to die when the Argo II crashed."
