Ib fearfully backed away from Mary, tripping over her own feet. The golden-haired girl stepped forward deliberately, a deranged cackle falling from her lips, which were spread in an impossibly wide smile. She had just slaughtered Garry, fresh red blood dripping from her knife in one hand, and a wilted blue rose in the other. Another sharp laugh, another step forwards. Over and over. Again and again. Ib was absolutely sure that in no way could the situation become worse, when Mary started to sing emptily, her words echoing throughout the halls.
Ring around the rosie
Mary picked Ib's red rose from the floor, tearing out petals one-by-one. Agony overwhelmed Ib. Tears streamed down her face as sharp knives stabbed her repeatedly. Over and over. Again and Again. Her vision tunneled, starting to fade. Mary leered at Ib as she collapsed to the floor. Another unhinged laugh echoed about the halls.
Pockets full of posie
Mary shrieked with laughter, shoving the petals in her pockets. She wanted a way to remember her dear, precious Ib once the black-haired girl was gone. My Ib. She rolled those words around in her head. My Ib. Over and over. Again and again. Ib now had tears rolling down her cheeks rapidly, hiccupping with silent sobs. She didn't want to die this way. With a maniac standing over her, and her friend dead beside her. No. No. Please. Don't do it.
Ashes ashes
Mary paused her progress towards Ib. A psychotic expression overtook her face as she sang that. Ashes…she turned towards Garry abruptly. She looked at the ground, letting out a static burst of crazed laughter. A lighter lay there, unassuming and plain. She snatched it up, turning it on and off. Over and over. Again and again. Garry had been the only thing blocking her from getting to Ib. Her Ib. Not Garry's. Hers. Looking at the broken body beneath her, she let out another burst of laughter. It was time to take revenge. Nothing was in her way. She flicked on the lighter, throwing it at Garry. Delirious laughter seemed to help it spread faster, consuming his crippled body. Mary turned back towards her prey.
We all
She took a step forwards, raising her knife. Ib cowered away, pressing against the wall, mind going blank. She thought of all the different ways this could end for her. More tears rolled down her cheeks. Over and over. Again and again.
Fall
Ib lay limp on the ground, silently begging for mercy. Mary took another step forwards, chuckling quietly. That soft chuckle soon turned to full-blown anarchic, wheezing laughter as she ran various scenarios through her mind. Over and over. Again and again.
Down.
With a shriek, Mary plunged the knife downwards, into Ib's chest. Her rose completely withered, and Ib let out one last fading sob as the knife hit its mark. Mary lifted it up, and thrust it down again. Over and over. Again and again. She carved out Ib's chest, sawing through bone, cartilage, and muscle, reaching the still heart at the center. Discarding the knife, Mary dropped to the floor in front of Ib. She drove her hand in to Ib's chest, clutching the heart, and extracting it. She clutched the heart to her own chest, smiling insanely.
"You are mine."
