Head thumping, Luigi managed to open his eyes again, unsure of where he was and what had happened. Wherever he was was it was dark, thick enough to not even see his own hands in and when he went to take in a breath all that filled his lungs was water. He choked and thrashed about to get to the surface, coughing upon doing so and clawing at the debri fallen beside him. He threw his torch up onto it and took a moment to gather himself. Throughout his coughs he called for his brother, trembling while gazing through the darkness.

"...M-Mario?"

He seemed to be alone, something he wasn't sure to be grateful for yet. With the lack of response Luigi retrieved his torch , whacking the side harshly to get it glowing .

"Come on, come on!" He frantically demanded, yelping as rubble fell to the water. "hn!"

Once it illuminated the room he darted it to the falling debri, flinching at the slightest sounds. Once he was certain that it was safe enough to take a moment to breathe he scanned around the walls and ceilings, hoping to see some way to get out of the water, but all that he could find were vines and mushrooms.

"M-Mario! I..." He stood upon the rocks and continued to survey the area, huffing loudly and following the vines. "...phone!, phone, yes-okay-"

He patted his pockets before brushing back his hair. He knew where his phone was, he knew where his brothers were as well. At home by the fire place.By pure chance he retained his satchel and gazed inside to verify he hadn't accidently slipped the devices in there. Most of the contents were missing, along with any signs of his phone.
Water still seemed to be coming from somewhere, rushing though not as intense upon his position, a sudden burst encouraging him to leap to the partially flooded walkway. The water leaked from a nearby wall of debri, a sight Luigi would have ran from if not for the sound of bitter frustration emulating from the other side.

“Mario?-" He spoke to which gained no response.

He cleared his throat and cried louder "MARIO!"

That seemed to gain their attention and the voice that responded was just as loud "i aint your stinkin brother!"

Regardless, Luigi was happy to atleast hear someone elses voice, even if it was Waluigi's.

"are you okay?!" Luigi asked, examining the wall with a few steps back. "what happened?-"

Waluigi didnt reply to either question, grunting aloud and seeming as though he was trying to move something.

"what are you doing?-"

"WILL YOU SHUT UP AND LET ME CONCENTRATE!" He spat back in a painful voice.

The water thrashing had at least stopped, still fiercely filling the room but less loud and more so making the ground rumble. At Least now he could hear the fearful whines of Luigi ever so louder. What a sound to die to.

“For fucks sake-” Walugi mumbled,feeling the base of the pipe trapped over his leg  and attempting to lift it slightly.

At first he managed to begin moving it, very slowly but still a shuffle. He only managed to do so 3 more times before exhausting himself. If he had only had his hammer he could shatter the thing right off him.

“...” He jolted at the thought “do you have my hammer?!”

“H-hm? Hammer?-i dont know” Luigi huffed, tapping the side  of his light with a wince before casting it to the further distance.

“Yea-”

It was just beyond the debri, the handle of the large hammer poking out from the sewage, its weight so heavy it scraped along the floor while he pulled it to the wall.

Waluigi grunted “use that to break the wall then!”

He tried lugging it on his shoulder.

“a-Ah!?” He immediately toppled over, slipping and falling on his back with a harsh splash “i cant-”

“I swear to God Luigi if you let me die in here I’m going to come back as a ghost and haunt the living shit out of you!-” As Waluigi barked, the water lifted, finally submerging the pipe pinning his leg.

Despite the leak, it appeared that the water was filling quicker than  it was escaping.

Luigi stood again, knees practically knocking together as all that his faint swing resulted in was a light tap hitting the brick. Even his loud grunts did nothing but further exaggerate the failure.

“...are you serious?!” Waluigi yelled, scoffing “im dead, im fucking dead! Wario!”

At this point Waluigi began yelling for his own brother, thrashing in the water and desperately pushing the pipe. It continued to shift, groaning.

Luigi scratched the back of his head, disguarding the hammer and thinking to himself.

"o-okay" He huffed before looking to his satchel once more, accounting for what he had on hand. "wrench- uh Duct tape- uh"

He further examined the wall, looking for a weak spot he could perhaps chizzle at. He looked to the bottom left side of the wall, begining to pull the rocks away and wedge his wrench through to pull away the debri. Granted the water pressure on the other side aided in flushing the rocks out it managed to further weaken the wall and gradually create a bigger hole. Occassionally the wrench slipped from his grasp with how much water was pushing through, however he managed to praise open a big enough hole to drain enough water and squeeze through.

"aye!" He cheered, rising his hands in the air and smiling to Waluigi.

He didnt seem very pleased "... my hero"

As he trotted over he observed the crushing pipe and furrowed his brow "..does it hurt?"

"what the hell do you think?!-" Waluigi replied, cutting himself off and wincing.

It seemingly pinned his legs, one significantly moreso. By the looks of it, Waluigi had managed to get it off the core of his leg but that only revealed the damage done. His left leg looked mangled, a clear break that almost knocked the wind from the boys lungs.

"o-oh"

Luigi's eyes widened in horror as he took in the extent of Waluigi's injury. He quickly kneeled down beside him, his hands shaking slightly.

"We need to get you out of here," Luigi said, his voice filled with urgency. "Can you walk?"

Waluigi gritted his teeth in pain, trying to shift his weight and put pressure on his injured leg. But the pain was too much, causing him to let out a pained cry.

"just get my hammer-"

"and what good is that going to do!?" Luigi yelped "there aint no way you could hit that from where you're sat! and i cant lift the darn thing-"

Luigi looked torn, torn between leaving Waluigi here and searching for help, or staying by his side and trying to find a way to free him. But he knew time was of the essence, and he couldn't afford to waste any more of it.

"and what- you're going to lift this pipe!?"
Luigi crouched down beside Waluigi, examining the injured leg with a concerned expression.

"We need to get it off your leg," Luigi said, his voice filled with determination. "But I don't know if I can do it alone. We need to find something to pry it off."

Waluigi winced in pain and nodded. After a few minutes of searching, Luigi's hand brushed against a metal bar hidden beneath some rocks. He pulled it out.

"This should do the trick." He positioned the crowbar under the pipe and braced himself.

"you just be carefull!" Waluigi demanded as it was pushed down with all his strength, grunting and exerting every ounce of power in Luigi's body.

The pipe started to budge, but it was still firmly wedged against Waluigi's leg. He gritted his teeth through the pain.

"dont worry- i got this-" Luigi's muscles strained as he continued to pry at the pipe. "I got this--"
