Mello immediately realized that he was wasting time listening to all of this. He looked around, and found a rusty nail embedded in between the cracks of the concrete wall. He inched towards the wall slowly by using his legs, and fell forward, pressing his face against the wall. It disgusted him to know that there was blood all over the wall, it stained both the rusted nail and the concrete. He didn't care at the moment, all he wanted was to escape.
Mello inched his head painfully towards the nail, and in a very awkward position, he took his front teeth, and grabbed the nail. It was stuck tightly, he knew he might chip his tooth from doing so, but he tried anyways. he pulled, hard, all of a sudden, pain shot down his back, but he ignored it. The nail tasted absolutely disgusting, metallic taste spilled through his mouth, but he also tried to ignore it. Finally, it was to much, he spit blood on the ground next to him, and tried again.
He pulled with all his might, and didn't chip a tooth, but he managed to get it out. The nail was in his mouth, then. He lifted his wrists to stab the rope with the sharp end of the nail, it hurt to even move his arms, but he tried anyways, and did stab it, in several places, trying to aim for the knot. He ended up getting to it, and he pulled up the nail with his neck, but he didn't get the double knot fully untied, he constantly worked at it, until both the first and second knot were untied, and the ropes fell onto the ground, victory was his.
He looked at his wrists, they were raw, red, and bleeding. It didn't feel nearly as bad as the rest of his body though. He sighed, and fell on the ground, so tired... he stayed awake, and looked at the two demons hopefully, they would help now.
