Chapter 19: Mine Sweeper

Izuku was walking through the Everfree Forest. He had to see Zecora for a reason. It wasn't that big of a deal, really.

Okay… so training "accidents" involing his quirk was still something he had to deal with. Sure he had Full Cowling now. But there were still times where he broke his bones. So... he needed the potions...

That was when he heard an explosion.

He headed to where it was and it was Katsuki.

He was doing his usual training.

Then he noticed Izuku watching him.

"What do you want Deku?" he demanded.

"I heard explosions so I wanted to see if everything was fine." said Izuku.

Katsuki grumbled.

"I'll see you back at the library." Said Izuku.

Izuku began to walk away when felt something off with the ground.

That was when suddenly the ground itself gave way breath both of them sending them down into a large hole.

"What the fuck!" yelled Katsuki as they landed.

Izuku looked up and he couldn't see the hole.

They saw they were surrounded by tunnels.

"Where are we?" asked Izuku.

"Underground." Muttered Katsuki.

"That makes sense." Said Izuku.

Katsuki just glared at Izuku.

"We should find a way out." Said Izuku.

"Whatever." Muttered Katsuki.

The two began to walk through the tunnels looking for a way out, the two did so in silence.

But as time went on it gradually became more and more tense between the two.

They found a chamber that had some rocks that look like they would make some decent seats.

"You seriously need to rest?" asked Katsuki.

"I have to think about this." Said Izuku.

Katsuki glared at Izuku.

"There's something off about this place." Said Izuku.

"What the fuck does that mean!" yelled Katsuki.

"It feels like it's constantly changing." Said Izuku.

"Yeah right." Muttered Katsuki.

He decided to leave.

"Wait Kacchan!" yelled Izuku.

"What!" yelled Katsuki.

"We need to stick to together!" cried Izuku .

"I can handle this on my own." Said Katsuki.

"I know you can but we really should stick together." Said Izuku.

"What's that supposed to mean!" demanded Katsuki.

"If we get separated and one does find a way out. There's no guarantee that we'll find the other or even the exit again." Said Izuku.

Katsuki glared at him.

"I don't need you looking down on me!" yelled Katsuki.

"What?" asked Izuku.

"I told you I can find a way on my own!" yelled Katsuki.

"You missed what I was saying!" said Izuku, "What do you mean looking down on you?"

Katsuki didn't answer.

"I never looked down on you! You're awesome!" said Izuku, "I always looked up to you!"

Katsuki glared at him.

"This isn't the time and place to talk about this though! We need to get out of here!" said Izuku.

"I told you I can find a way out myself." Said Katsuki.

That was when Izuku heard something.

"Aren't you going to say something Deku!" yelled Katsuki.

Izuku put his hoof to his lips and Katsuki stopped talking.

That was when he heard what Izuku was hearing.

It sounded like faint laughter.

They looked at each other and realized they weren't alone in this network of caves.

Both of them tried to sneak on the laughter.

It was behind a wall, but the wall was pretty thin.

"They're finally turning on each other! This is perfect!" they heard the voice laughing.

"We need to be quiet… they hear us!" said another voice.

"They're so focused on each other, besides we already buried this area… they won't even notice us." Said the first voice still laughing.

The two human turned ponies looked at each other.

Then Katsuki blew up the wall.

It was clearly it was just a mound of dirt and not rock, but it did its job. The wall was gone… and behind the wall was Rover and another smaller diamond dog.

"I'm going to alert the queen!" yelled the smaller one.

"Pay no attention to the dog behind the wall." Said Rover.

Katsuki grabbed Rover.

"So Deku was right, it was changing." Said Katsuki.

"You're trapped here now!" said Rover, "The plan might have failed but the queen will defeat you!"

"I don't care what the queen can do!" yelled Katsuki.

That was when suddenly he was ran over by something.

"Kacchan!" yelled Izuku.

Katsuki blew up what ran him over.

"A fainting couch!" said Izuku seeing what was used a weapon.

"You're lucky that's an old one…" said the Diamond Queen showing up.

"So you're the one trapping us here." Said Izuku.

"Of course. It was such a simple plan. Trap you in my catacombs and then have you either turn on each other or wait until you were starving." Said the Diamond Queen, "But someone had to give it away."

"What happened to you?" asked Izuku.

"What do you mean what happened to me? We've never met." Said the Diamond Queen.

"You could have been a good person." Said Izuku.

"What makes you think that?" asked The Diamond Queen.

Izuku as about to say something, but then his voice just failed him. It was weird. Then he remember why.

"Deku!" muttered Katsuki face hoofing.

Original Starlight's "curse" he couldn't tell her anything about the original timeline.

"I forgot." Said Izuku regaining the power to speak.

"I don't know what just happened but there was no possible way to be a good pony." Said The Diamond Queen.

Her horn glowed and suddenly gems from all over started start to swarm them.

"You're in my domain… even if I wasn't able to weaken you, there's no way you can beat me!" said The Diamond Queen.

She began to pelt the two with gem stones.

"What the fu…" yelled Katsuki.

"Language!" yelled the Diamond Queen whacking him in the face with one.

Izuku created a forcefield.

"Super strong and powerful in magic… it's a shame that we're enemies. I wouldn't mind keeping you." Said The Diamond Queen.

She did continue to lob the gems at the two in the hopes that it would shatter the dome.

"Bring the shield down." Said Katsuki .

"We need to come up with a plan to beat her and get out of here." Said Izuku.

"I have a plan!" yelled Katsuki.

Izuku noticed he seemed to pooling sweat in his hooves.

"But Kacchan!" yelled Izuku.

Katsuki glared at Izuku.

Izuku sighed knowing that Katsuki wasn't going to listen to him.

"I'm going to teleport away!" said Izuku.

"That's even better." Said Katsuki.

Izuku took a breath and teleported away.

But not too far away, so that his fears of what the attack might do.

Katsuki let loose the biggest explosion his could sending all of the gems flying.

While the Diamond Queen was distracted he ran over and gave her the biggest punch he could.

He turned to Rover who was quivering.

"Now…" said Katsuki, "How do we get out of here."

However thanks to the explosion suddenly the celling started coming down.

Katsuki stared at the rocks, which were suddenly bathed in a green light and flew away.

Katsuki glared at where Izuku stood as he knew it was where he was who sent the rocks away.

"I tried to warn you that you might cause a cave in." said Izuku.

Katsuki gritted his teeth and looked away.

However both of them noticed the natural light coming through.

"One good thing came from it though." Muttered Katsuki.

Izuku brought back the rubble he pushed and used the rubble to create a set of stone stairs.

Katsuki stared at the stairs.

"Twilight's been teaching me magic like this." Said Izuku blushing.

"Don't rely on it." Said Katsuki, "It's going away when we get back home."

"I know." Said Izuku.

They both went up the stairs.

As they did.

"My queen!" yelled Rover.

"Drat!" she said still alive thanks to her cloak, "All that time planning!"

She pulled out a fainting couch from somewhere.

"It was the perfect plan!" cried the Diamond Queen.

"Don't worry my queen your next plan will work." Said Rover.

Back on the surface, the two saw Ponyville in the distance.

"Kacchan." Said Izuku.

"What." Muttered Katsuki.

"About what you said about me looking down on you." Said Izuku.

Katsuki glared at him, silencing him.

"Okay… I won't ask." Said Izuku.

They both headed back to Ponyville… with Izuku realizing there might be an underlying issue between them.

One that Katsuki would not talk about, especially not any time soon.

Izuku could only hope that they would be able to talk about it one day…

Oh there was one little tidbit he got when Izuku decided to tell Twilight and Spike about the fight as he felt they had to know.

"Wait she used a fainting couch as a weapon." Said Spike.

"Yeah." Said Izuku.

Both of them started to laugh, confusing Izuku.

"Sorry, sorry…" said Spike.

"Just… something we have to tell you about Rarity… something that clearly didn't change between timelines." Said Twilight.

The fight also gave them a little hope. That maybe the Rarity they knew was in there somewhere…

Even if it had to do with her thing for fainting couches, which was something that did greatly annoy the two of them about her… But hey, it was something…

Next Time: It's time for the Grand Galloping Gala. However as it's something heroes have to do sometimes, they have to go. Will they be able to have a pretty decent night? Find out next time!
