Despite the blood and the glinting shards of mirror protruding from his knuckles, Charlie's hand didn't hurt - or, rather, in the moment, with the shock, and the adrenaline, and all the thoughts and the feelings coursing through his head, the pain didn't register for him. Arthur's emergence into the bathroom didn't seem to register either, nor did his touch, as the instructions desperately put forth seemed to do nothing but roll over the fractured man and dissipate, like whispers in a hurricane.
Some of the shattered mirror still remained in its frame, cracks running across it and warping the picture it reflected back as Charlie continued to stare at his own, distorted image. His breathing was heavy, his body still stiff with tension. A thousand thoughts seemed to simultaneously shout within his mind, chief among them the unrelenting idea that the whole situation - the mirror, and his earlier outburst, and his inability to remain calm - had revealed him to be the ruined, pathetic, shadow of his former self that he knew himself to be, and that Arthur now knew it too. Soon, the whole country would know it, when he got up in court and inevitably found himself losing control there too, because what kind of man did this? What kind of man couldn't keep his composure to such a degree that he struck out at inanimate objects and spat words at those closest to him? A failure, that was what.
Charlie didn't think as he raised his fist again. His arm pulled back, shaking off Arthur's touch that, under any other circumstance, should have been the comforting element he needed to snap himself out of the volatile trance he found himself in. Where exactly he was aiming as he swung forwards again, he didn't know - certainly not at the mirror, so the wall most likely, as it was the next nearest target. In the end, it didn't matter, as Arthur manoeuvred himself directly into the path of his fist, intercepting the blow and, while not negating the effects of it entirely, saving Charlie from doing greater damage to himself.
Arthur's flesh was soft, and the impact with it was undoubtedly less traumatic than the alternative - that being, Charlie colliding his knuckles, already damaged and with nasty slivers of glass sticking out from them, into the cold, hard tiles of the bathroom wall. As his fist met the other man's face, the impact immediately registering and Charlie's expression contorting into one of absolute horror and regret, said glass broke further, some shards embedding in Arthur’s cheek, others grinding deeper into his own knuckles. Now, he felt the pain. It shot through him like lightning through his veins, amplified by the visceral shame he felt for what he'd done - guilt given form and teeth, setting every nerve alight, as though his body itself wanted to punish him for what he's done.
"Fuck. Fuck, I'm sorry." The apology came out of reflex. There wasn't yet any serious weight behind it, but that would come soon enough. Once the shock of the moment wore off, and the seriousness of what he'd done began to weigh him down like a ball and chain, there would be a thousand apologies - none of them, in Charlie's mind, enough to repent for his actions.
Wide eyed, he raised a hand as if to touch Arthur's face, before hissing in pain and looking down at his knuckles. Blood streamed down Charlie's arm, running down the inside of his shirt sleeve and leaving a stained trail in its wake. Without thought, he went to pull out one of the shards of glass that, thankfully, still just about stuck out above the skin, then immediately made a pained noise and drew his hand back, shrapnel still left embedded in the wound and blood now slow swelling out of a cut on the finger that had come in contact with it.
Looking back at the other man, the sharp cuts to his upper cheekbone and the skin that would undoubtedly soon bloom into a deep, violent bruise, reality began to skin in. What had he done? He could have blinded him! Arthur was never going to forgive him for this, was he? And why should he? Even with a stranger, this would have been unforgivable, but with a lover? Charlie had well and truly fucked everything up. He'd ruined everything, and he didn't even have a good excuse to explain why.
"I'm sorry. Let me help you. Where's your first aid kid? I'm sorry."
There was, at least, one silver lining - that being, the horror of what he'd done had snapped Charlie out of his prior mood. Now, instead, words laced with concern tumbled out of his mouth without pause, all signs of anger gone and any nervousness remaining attributed to the bloody mess before them instead of the court case he was about to face.
