With Pound and Flurry Heart trying to look for a way out of the cave, they don't know if the sun already went down or not, they were getting hungry too.
Suddenly they saw a split in the cave with three ways, then they decided to go left, seconds of walking, "Pound, I'm hungry".
"Me too, but there's nothing to eat in a cave", he told her, she didn't say anything and they continued to walk.
Back with Twilight and everypony else in the swamp, they continued to look for the Pegasus colt and alicorn filly, "Pound...Flurry Heart", there was no answer back.
After a hour of searching, they decided to call it a night turning in and decided to continued looking in the morning.
With the Cake's, "Mommy...daddy, did you find Pound and Flurry Heart yet?", the little unicorn filly asked.
Her father sighed, "We haven't yet, but they're out there somewhere".
Minutes later they headed for bed, a heart broken Mrs Cake hugged her husband in tears, "I can't believe my little boy's out there somewhere".
"Don't worry, we'll find him....just hope he and Princess Flurry Heart will be alive when we do", he kissed her head.
Back with Pound and Flurry, suddenly they were tired and yawning, suddenly they started hearing noises causing them to be alert looking everywhere.
Suddenly the little Princess felt hands grab her and lifted her up, "Pound, help me", she cried being carried away with her hand stretched out to him.
The boy noticed that she's being taken, he lunged for her hand only to be grabbed also, he was being dragged away also.
"Flurry Heart".
"Pound", they were going through the same tunnel.
Minutes later of asking where they were being taken too, they reached a tunnel that has lights, "Where are we?"
"You're in Diamond Dog territory", the kid's were able to get a good look at them thanks to the lights, they had pants and vests and looked like dogs.
"Where are you taking us?", they then came across a least a dozen of cages, they had children sleeping that been missing for a few years, and there clothes were ragged and dirty.
Then the two kid's got stuffed in two empty cages across from each other, they noticed it had a ragged pillow and blanket, also a bucket that smells really bad like urine and poop.
"Let us go, please", the little girl begged.
"Be quiet little pony, or else you'll be punish".
"What are you going to do to us?"
"Tomorrow you'll have one job and one job only, dig for gems".
"Yes, dig for gems", a dog creature then gave them a small thing of food that they can eat, the two hesitated before they started eating.
"If we dig, are you going to let us go afterwards?", the little boy asked.
They started laughing walking away, "You'll stay here forever, and forever digging us gems", then they turned a corner out of site.
"I wanna go home", the little girl said scared, she was thinking if she'll ever see her family again.
"I know, me too".
"We're never leaving this place", they heard a earth pony boy say, they noticed he was three years older then them.
"What do you mean?"
"Me and my sister been here for three years", the older boy spoke trying to fall asleep again.
"Where's your sister?", Pound spoke.
"They killed her two years ago....she wouldn't stopped crying and begged them to let us go, they dragged her away and never brought her back, I tried to save her but I couldn't".
"I'm sorry for what happened to her", Flurry spoke frowning.
Then the earth pony boy reconized her, "Ain't you Princess Flurry Heart", the alicorn filly nodded.
He got up, "Are guards looking for you....if so, then that means we'll be saved", he asked with hope.
"I'm pretty sure they're looking for me and my friend, but I'm not sure they don't know where we are".
He frowned, "Oh....guess we'll work here as slaves forever then", he layed back down going to sleep.
The two kid's finished eating and decided to lay down too, "Pound".
"Yeah?"
"Will we ever get home?"
"I hope so Flurry", then they layed down too.
The Pegasus colt just layed there, he wanted to go home and wished he never went to Foggy Bottom Bog a second time, and especially brought Flurry Heart along.
The next morning, they were woken up by the dog like creatures, "breakfast, and hurry up and eat so you can get back to work", they started passing out food to the kid's.
They started eating, seconds later they formed a line and there ankles got put in shackles, then started walking towards a pile of pick axes.
The kid's picked one up each, "Follow Spot", the dog like creature started leading them towards a different tunnel.
Minutes later they stopped, "Dig gems here", Spot pointed at a wall and they started digging.
Minutes later, "I-I have to use the restroom", Flurry spoke up.
"No breaks till you find at least ten gems", Fido told her.
"B-But I have to pee".
"Don't care, now start digging or else", he threatened, the little alicorn girl continued to dig.
She closed her legs and started moving her body up and down, seconds later she couldn't hold it and relieved herself.
When the Diamond Dogs noticed the wet spot growing, they started laughing, "Ha...the little pony peed herself", they only found it funny and the kid's didn't.
The poor alicorn filly felt tears in her eyes before she started silently crying to herself, the creatures started calling her names.
Pound noticed this and turned to them glaring, "Leave her alone", they stopped turning there attention to him.
"Did you just talk back to us", Fido walked up to him letting him out of his shackles.
"Spot, Rover...take him to get punished, five lashes", the two Diamond Dogs nodded before dragging the boy off.
"Where are you taking him", Flurry asked.
"They're gonna whip him", a unicorn boy spoke up.
"What?"
"Talking back is worth five lashes across the body", the alicorn girl became concerned for her date.
Seconds later everypony could barely hear, "Let me go, please", then whipping noises echoed throughout the tunnels along with the little boys cries of pain.
A few hours later with a couple of Royal guards close to Diamond Dog territory, they were looking for clues when suddenly they heard a couple of voices from behind a hill, they decided to check it out.
"Have you heard, we got two new workers".
"Yeah...a Pegasus pony and a weird one".
"Weird one?"
"Yeah a weird one, she has wings and a horn...you know what, I think she might be related to those two alicorns in Canterlot"., the guards hid.
They knew exactly who they're talking about, "They must have the Princess and that boy she's dating"., his fellow guards nodded.
"You and you stay here and keep an eye on them, while me and Rose let the Princess's know"., the two nodded before his comrades took off.
Soon in Ponyville when they finished letting their leader and Captain know, "Somepony has my baby as a slave worker", the two nodded.
"Yes Princess, and that boy she was with".
Suddenly Rose perked up, "Wait....didn't that dog creature say two new workers", her fellow guard nodded.
"Think they might have those kid's that disappeared a few years ago", the Princess and her husband started thinking.
"Get as many guards as you can, we're gonna save my daughter and those lost kid's", the two guards saluted before leaving.
Cadence and Shining started getting prepared for a rescues as they became angry, "Those creatures are so gonna pay", her husband nodded.
