"Are you okay, sweetheart?" Phoebe asked as she rushed over to help him up.

"Yeah," he nodded.

Grace-Anne then kneeled down to get a good look at the stone staircase. The open itself was about as wide and long as a large cardboard box with a descending stone staircase. Each step disappeared more and more into the dark underground, and the cold dampness cut through the jungle's humidity. Pulling out her flashlight, Grace-Anne switched it on and shined it down the staircase. Nothing out of the ordinary except for a few dead snakes, but she felt uneasy about immediately taking the steps down.

A rock sat idly next to her, and it was immediately serving as a guinea pig. She tossed it down where it could still be visible by the light beams. Landing on a stone in one of the steps, it sank down halfway, and a spear shot up from the middle of the stone. The rock was split into two pieces before falling away somewhere.

"Do any of the notes say anything about this?" Grace-Anne asked as she stood.

Hongjoong was already ahead of her and reviewing the notes on both the map and the journal.

"Yes," he nodded once he found the page. "Any of the stones with a golf-ball sized hole in the center has a deadly spear. Have your flashlights ready."

One by one, the crew switched on their lights just before descending down the stone steps, tip-toeing over each holed stone. The air seemed to grow colder and more dense, and a soft blue glow could be seen up ahead. When they reached the bottom, a foul stench attacked their noses as they turned a corner.

"If I see one more corpse," Dinah threatened, "I will kick a stalagmite."

"I don't think it's a dead body, we're smelling," Grace-Anne replied as they walked a little further. "It smells more like mud after the rain."

The sound of a river rushing could be heard overhead. Hongjoong used his flashlight to read the notes again. "The blue light tells us that's where the next piece is."

"What is that light anyway?" Mingi asked as they strolled closer to the light.

"Yeah, there doesn't seem to be any electrical fixtures down here," added Yunho.

An opening marked where the blue light was hiding, and once the crew walked in, the light turned out to be what seemed to be twinkling blue clusters sticking to the wall and reflecting off of clear quartz fragments blooming from the ground to the ceiling. With this kind of light, the crew switched off their flashlights.

"Glow worms, of course!" Dahae recognized. "Their bioluminescence gives off a sort of blue or green light."

"But where's the diamond piece?" Seonghwa reminded her as the crew looked around. "It could be anywhere here."

Jongho was about to try to move a quartz piece to investigate any nook and cranny, but Dahae stopped him with a gasp.

"What's wrong?" he asked.

"These aren't just any of the regular glow worms you hear about," she explained. "These quartz's have minerals that provide this species with their nutrients, and they're aggressive if they're touched by any other living organism. Touch the crystals, and a few of them will attack."

"They're not poisonous, are they?"

"They just give you deep cuts, but the bleeding is bad no matter where the laceration is."

"Found it," Taeran declared as she looked up something in the ceiling.

Surrounded by clusters of the glowing blue, a shining fractal seemed trapped in another microvine structure surrounded by crystals. Beside it was a sort of lock code identical to a lock combination, but rusted into the ceiling.

"What's the code?" Dahae asked.

Hongjoong flipped through the journals and notes a few times, scanning each page individually in case he missed it. He found something on the exact lock, but no direct answer as to free the diamond.

"There's a riddle," he shrugged as scratched his head. "'Not a full circle, not an angle, not even a cute angle, only a straight path will you find the key.'"

"What path?" Dinah exasperated. "The only way out is the way we came in, and even then it's deadly."

"And we can't exactly pry open the little binding it's in without touching the surrounding crystals," Grace-Anne added.

"Maybe it's talking about the sun, hills, and a path on a hill," Seonghwa guessed.

"We're in a freaking CAVE!" Dinah retorted while motioning towards their surroundings.

Taeran stared up at it and recited the riddle. Circle, angles, path. Circle, an angle, a cute angle, path. A cute angle stuck out to her. Did it mean an acute angle?

"Wait a second," a lightbulb went off in her head. "It's not a regular piece of land at all. It's geometric angles. A full circle is three-hundred and sixty degrees, a cute angle is an acute angle that's forty-five degrees, and a right angle is ninety-degrees. What we're looking for is the straight 'path,' and it's a straight line. One-eighty degrees."

"1-8-0 is the code?" Phoebe asked.

"It has to."

"How are you going to reach it?" Dahae wondered. "The ceiling is taller than Yunho and Mingi."


Finishing up in the bathroom, Celestia took one last look at herself in the mirror, double-checking for any fly-away strands of hair before standing back and seeing her pregnant self. Her stomach wasn't as huge as a typical pregnant woman's, but she still found it cute despite feeling like a bloated fish some days. Baby girl kicked, and the mother-to-be smiled.

"You're so gorgeous," San commented groggily as woke up.

"Hi, handsome," his wife replied as she waddled back into the room.

The curtains were opened just slightly to allow some sunlight in, but not enough to disturb San in his sleep.

"How are you feeling?" Celestia asked as she eased herself on the bed.

"Better."

"You look better, too. Your color is back. Are you sore?"

San shook his head. "I can move more freely, but it only stings when I move my back a certain way."

"Dahae said it'll be like that for a bit, but you'll be back to exploring our next destination."

A smile nearly bloomed on the young man's face, but abruptly stopped. He wanted to see the new site, but Celestia couldn't go anymore when she's days from delivering.

"I don't want you to be alone," San shook his head.

"I won't be alone," she promised. "The girls will rotate out on who stays with me at each stop."

"But what about when it's time for you to give birth? We would have to flag down an ambulance or something to get you to a hospital if needed."

San had wanted his wife to give birth in a medical facility that was safe, and she and the baby would receive proper care; but Celestia had put her foot down on having the birth on the boat since Dahae would help with delivery. However, she was becoming more open to having the aid of a medical facility if things were to go wrong.

"I've heard you can't plan for how a birth is going to go," was all Celestia could say. "But we can be prepared."

San just smiled and kissed her on the cheek. "Such a clever woman, you are."

Celestia scoffed playfully before asking, "Are you hungry? Grace-Anne left us some breakfast."

"Can you get up?"

"Watch me." Immediately she scoot to her edge of the bed, sat up, and rolled to one side to stand. "Cake."

San giggles as the love of his life waddles out of the room and towards the kitchen. Celestia found her meal of eggs and Greek yogurt covered in plastic, and San's bacon and omelettes were in the same shape. She removed the covering and put them in the microwave for about a minute while she retrieved both of their drinks.

A fit of childlike giggles erupted from San back in the bedroom. Celestia thought his medicine was making him loopy until he started baby-talking and cooing in his mother tongue. Was he looking at the ultrasounds and somehow talking to the baby? It wasn't until she returned with their breakfasts when she saw what had happened.

"Angel, we've got a little stowaway," San smiled as he was now petting a Siamese cat sitting on his stomach. "Isn't she cute?"

"She is," Celestia smiled as she set the food tray on San's nightstand. "Hi, kitty."

She held her hand to the feline, palm open and face up; and after a couple of sniffs, the cat licked her fingers and rubbed her face against Celestia's hand.

"Friendly, aren't you? How did you get on here?"

"She must have wandered up the landing gear from outside," San guessed. "I managed to sit up, because I had to pee; and when I came back from the bathroom, there was a super cute cat sitting on your side of the bed."

Celestia gave the purring cat a few more scratches behind her ears before thinking for a moment.

"What's the captain gonna say?" she asked as she sat on the edge of the bed.

The captain had a thing with animals on the ship. It wasn't that he didn't allow it, it was that everyone had a job to do and wanted everyone to always stay on task that getting a pet for one crewmate or for all to share seemed impossible. Everyone, including Dahae, had begged Hongjoong multiple times for a furry friend, but he always said no.

"Well," San thought, "I mean we already have a baby on the way, so he might say our new friend has to go; but since you're going to be here on each stop, maybe she can help keep you company."

As if excited by his idea, the cat leapt off of San's lap and tip-toed to Celestia's bump. She began to purr as she rubbed up against it. It was as if she now knew there was something precious being nurtured and developed in a protective shell.

"I think we might have found our guardian for Baby Choi," San jokes with a chuckle.
