There was silence in the Ravenclaw Tower as a war waited to break throughout Hogwarts. Amycus Carrow struggled against the silver rope which simultaneously bound him to his sister and prevented his escape. The rope grew tighter still the more he fought against it, and yet, he managed to pull out the wand hidden within his robes (which he had confiscated from a first year student earlier that day). He was glad of the Dark Lord's insistence that his followers learn to resist the Imperius curse, or he would've handed the wand over to Minerva McGonagall along with the other two; she had been surprisingly easy to fool.
Despite the strength of McGonagall's spell, after a few tries the rope slid, gleaming and lifelessly, to the floor. Amycus then turned to his sister who - although freed - was still unconscious, ignorant of the fate that waited for her (and himself) if they failed to hand Harry Potter over to the Dark Lord.
'Rennervate,' he said quietly – he wouldn’t put it past McGonagall to post a guard nearby.
Alecto's eyes flew open at once. 'Amycus,' she said in a hoarse voice as her eyes darted nervously about the room. He watched as her expression morphed into a look of pure terror when she realised the danger they faced. 'What’ll we do?' she rasped. 'The Dark Lord... he... he...'
'He won't do nothin' as long as we hand him Potter.' Amycus failed to keep the fear from leaking into his voice. 'I say we split up and find him.'
Alecto nodded her head, still wide-eyed, and allowed her brother to pull her to her feet. 'We have to get to Potter first,' Amycus said, managing to sound stern. 'Don't let no one get in the way.'
Alecto nodded once more as they cautiously exited Ravenclaw Tower. To their surprise they met no resistance once outside, and were able to safely part ways at the end of the staircase.
