'You're never wanted to hurt me?' Severus snorted haugthtily. 'You could have fooled me - if it wasn't because I've let you do that for the last time! I can't believe I've let you touch me!' Severus' heart was contradicting his words, it did hurt to see the beast so sad, but Severus ignored it. What did he care a Dark Creature looked sad. Dark Creatures should be destroyed and they had no feelings, just something that looked like it, so they could lure decent wizards to do things they had wante- Severus cut that line of thought off. Of course he had been lured, and his feelings weren't real, just as the beast's weren't. They were just weak copies of real feelings - or so Severus tried to tell himself.
'And how do you propose to do that? Fix things? I can't see anything broken here, but that can be arranged!' Severus' eyes grew even colder. He pointed at the beast. 'Sectumsempra', he cried, aiming the hex at the beast's face. Oh, there would be things broken now.
