Coal: There are heart wrenching sobs echoing throughout the bedroom. The bump sticking out of the blanket trembles with every wrecking sob. Coal feels his soul clench with pain and self-hate with every breath he takes.
how could he have been so stupid? so horrible? how could he do something so horrible to you?
Shame, guilt, despair, remorse and self loathing spreads through his entire being like a sponge soaking up water when the image of what happened floods inside his head.
You’ve been so secretive lately, making a lot of excuses like going to work, or out with friends, or buying something, visiting family etc. And when you were home, you often were too busy with things to hang out with him. Now Coal wasn’t as good as his brothers when knowing someone’s lying, but he knew that you were hiding something from him. After all, Coal knew your work roster like the map of his favorite video game. (Always writing it down in his little remember book when you tell him the day you need to work so he can create some free time on the days you are free.)
But you’ve been making the excuse to go to work when it wasn’t even the day you were supposed to go to work. It just didn’t add up. Your eyes didn’t quite shine as you told you excuses, which only happened when not being completely truthful. And Coal didn’t understand why you were lying. You were hiding something from him, not telling him the full picture, and he hated it.
Coal trusts you completely. He can say with confidence that he’s not worried that you’re cheating on him or doing anything to hurt him. He knows you, he loves you, he trusts you, and he knows you love him too. Coal just couldn't stand the fact that you were keeping something from him. Was it because you were worried, he would get worried? Was it because you didn’t want to bother him? Did you think he couldn’t handle whatever it was? Or that he would think any less of you because of it?
he should’ve set you down and seriously asked about it and explained why he needed to know instead of just casually asking.
Every time he offhandedly asked if something was going on, you kept saying that it was nothing and that everything would be fine. Coal trusted you completely. He just couldn’t stand being left in the dark from anything any longer. It had happened more than enough. Coal had let it fester until he exploded.
“what the hell’re ye hidin’ from me!?” Coal had snapped one day when you were about to leave again. He wasn’t angry at you specifically, but at a lot of things at once. All his life everyone had kept secrets from him to ‘protect’ him. Everyone knew stuff that he had no knowledge of. Everyone keeps things to themselves or hidden to ‘spare poor, fragile’ Coal.
As if he couldn’t handle anything just because Razzle has protected him for so long.
Who had been the one who was there when Razzle bent and buckled from all the responsibilities and guilt he had to carry solely on his back? Who helped him stay afloat and supported him when he found better coping mechanisms instead of diving himself into more work? Who had been the one who managed to break through Mastiff’s unhealthy wall he bricked himself into? Who helped and supported Mastiff as he worked through his issues? That’s right, it was Coal. He was the one who was there behind the scenes helping. Coal was not poor nor frail. And he felt done, being treated as such.
And you were left aghast by his outburst. You never had seen Coal act like this, he wasn’t one to get angry. Frustrated yes, but not angry. You had tried to calm him down, explain that truly, you hadn’t kept anything hidden from him with ill intent. That you had been trying to get together and create a surprise for him. But whatever you told him, it barely registered. He was unable to be pacified.
And as he started to tug at the laces of his thin jacket hoodie- a habit of his, indicating he was frustrated and stressed - you tried to reach out, worried. But the moment you touched his arm Coal had harshly slapped it away. Putting a bit too much strength into it as he shouted “don’t touch me!” What happened next was all a blur for Coal, only remembering fragments: His soul being squeezed with horror and guilt, the tears in your eyes and Coal running away. Hiding underneath the blankets of his bed as pressed his head into the pillow. Sobbing in anguish.
Coal doesn’t know how long he has been hiding there. He doesn’t really care anyway. He has ruined everything, he has hurt you. He has made you cry. And Coal felt like the worst being in the world.
Coal feels the bed sink a bit, and he already knows who it is.
“go away.” He curses his voice for breaking and not sounding angry at all. It was like a pathetic yelp.
A grunt was heard, and a hand was placed on his side. “no can do, ‘m check up crew.” Mastiff tried to be lighthearted, trying to make light of the situation because he knew something was up.
It was silent for a long moment, only Coal’s sobs and hiccups broke it until Coal spoke up once again.
“…i ruined everyhin’…”
Mastiff didn’t say anything. What could he say? He wasn’t good with words or with comfort. That was Coal’s thing. The only thing Mastiff could offer was his presence and the hand on Coal’s side. Listening to his brother’s heartbreaking sobs.
✨✨
Mastiff: Mastiff hated what he felt so often. It did you dirty and you don’t deserve that. He trusts you fully, he does. But he can’t deny the ever present thought of dread hiding in the deepest corner of his mind.
all this will be taken from him in due time…it won’t be long till something far better then he could ever be comes by.
And it happens…but, you don’t want better. You have only eyes for him. And mastiff feels his soul soar into the clouds. He pledges his unyielding loyalty to you only. He’ll be the shadow that has your back. But you shake your head with a smile as you drag him out into the light, having him stand by your side. And mastiff has never felt something that felt so right. Yet, he finds it slowly cracking before him. He doesn’t realize it’s by his own doing, his own insecurities that caused the cracks until it’s too late. And it started when Coal asked with curiosity one day what sort of game it was the two of you were playing. And it was like a head dive straight down from there. Coal started to hang out more, at first Mastiff didn’t mind, he liked having his twin brother around more, genuinely enjoying something together.
But…
But you really enjoyed Coal’s company too…and a voice in the back of Mastiff’s mind started to whisper things…Things that he couldn’t just ignore… Things that played heavily into his insecurities…Things he was too scared to ever confide to you, even though he made a promise to do so whenever something bothered him.
now that Coal is in the picture, you won’t be needing him for much longer.
Mastiff hates these thoughts with a passion. He thought he was done feeling like he’s standing in Coal’s shadow. He thought he was over it!
Apparently not…
Mastiff hates how he’s having a grudge on Coal, who has done nothing wrong. He hated how his mind could dare to think that you would go for his brother. But…he especially hates how he snapped at his brother, who could only utter a confused; “w-what…?” At Mastiff’s sudden outburst, growling and snarling as if Coal was about to steal from him.
“haven’t ye got enough!? not only are ye fuckin’ blessed with luxury i could’ve only dreamed of, now ye wanna take what’s mine too!?”
But what made him hate himself the most, was the way you had to bare witness to this disgusting side of him. Of course you stood up for Coal, standing between both him and Mastiff to break it up. But that had set Mastiff off even more. His fear of losing you lashed out in the most horrible way possible.
“what, yer takin’ the copy’s side over me too? this a gang up on me now?” He throws his arms up, glaring at you while he barks out the words. “why not! all is taken from me anyway, what’s one more time, eh!?”
You’re angry too, obviously, but you make the attempt to communicate -
“Mastiff! Stop this-!“
Unlike what Mastiff’s doing…he’s causing a self destruct.
“why don’t cha give ye boytoy a smooch, eh? see if he really’s better than me.” He leans in really close, flashing his very sharp fangs. He’s not thinking clearly, acting on the anger, on the betrayal, on the insecurities. It’s like a heavy fog is clouding his rationality.
“ye got whatcha wanted. enjoy while it lasts, slut.” Mastiff snaps his jaw shut in your face, making a loud clack. He leans back, and inside the fog there’s a voice filled with terror screaming at him to backtrack immediately, but he’s too far gone.
He’s looking at your face. He sees the shock, which transforms into betrayal and hurt. Tears are slipping past your eyes fast. And a truck could’ve rammed into him and ran over him twice and it wouldn’t have made a difference. Your voice is soft and broken as you whisper: “Y-you…how could you-I - I gave you my everything…” you don’t finish your sentence, you turn and sprint out the room. Leaving Mastiff frozen in place due to the horror of this reality. Mastiff feels as if he could fall into the Core and it wouldn’t have mattered. He feels like he’s worse than Gaster.
He wants to run after you, but Coal withholds him.
“what are-!”
“trust me…ye don’t want to hurt them more then ye already did, bro.”
Coal is hurt too, but he pushes it to the side to be the one to protect his brother for once. Mastiff is sinking to the floor, “what have i done…” it’s barely a breath that leaves past his teeth, but Coal hears it either way.
Coal follows his brother, holding him tight against him. Mastiff lets him, clinging onto the comfort like a life line. “ye done a lot, that’s what ye did.” Coal mutters back. “and ye’ll have to apologize and salvage what’s left eventually…”
