His heart hammered in his chest every time his skin brushed hers, an unknown force made it feel like he was being tugged towards her from the inside out. His whole body slumped in relief when he heard the shallow inhale of her breath again, Theo's healing charms working perfectly. Draco had known they would, his best friend had healed his kidney twice after being kicked violently when he didn't dodge one of Nott Snr's jinxes in time and then again the next day when the old man had discovered Draco to be healed. From then on the boys healed their injuries and faked them for a few days till he forgot what injuries they were supposed to have. External ones were trickier, they had to heal the cuts that didn't stop bleeding then make similar cuts on each other that were just superficial. Draco had become the pro out of the two of them for the blood wounds. He set to work knitting the skin back together where Potter's spells had gone too deep, in all fairness there was only one that bled continuously on her forearm, the rest were just minor cuts along her ankles.
