Calleigh shook her head yes. He didn't know why, but Harry didn't do anything. He had a perfect chance to get his vengeance on Sirius but he hadn't.
"I don't deny it," he said very quietly. "But if you knew the whole story. Or even remembered that night, you would understand."
"They whole story?" Harry repeated a furious pounding in his ears. "You sold them to Voldemort. That's all I need to know."
"You've got to listen to me," Sirius said, and there was a tone of urgency in his voice now. "You'll regret it if you don't…. You don't understand…."
"I understand a lot better than you think," said Harry, and his voice shook more than ever. "You never heard her, did? My mum… trying to stop Voldemort killing me… and you did that… you did it…"
The minutes passed, and Calleigh finally got up, pushing past her father, look very ill.
"Harry, what did I say to your Aunt Marge that night that the Dursleys had invited me to dinner with them?" Calleigh mumbled weakly.
"Yeah, you had told her not to base opinions off of second-hand knowledge. I don't see what that has to do with this," Harry replied disgruntled.
"Well then take it into consideration. If you won't do it for him, at least prove me wrong then and let him tell us what happened," Calleigh coughed, before double over onto kneeling on the ground again in dry heaves.
Sirius bent down, mumbling words to Calleigh as she was doubled over on the floor in dry heaves. He seemed to be comforting her. The whole while, no one else seemed to move.
"I'm fine," she muttered before she went into another set of dry heaves.
A new sound came. Muffled footsteps werew echoing up through the floor – someone was moving downstairs.
"We're up here!" Hermione screamed suddenly. Though, they probably realized that when they found out that Calleigh's coughing was coming from above.
Harry should have done it just then, but he couldn't bring himself to do it with the sound of the thundering footsteps in the back of his mind.
The door of the room burst open in a shower of red sparks and Harry wheeled around as Professor Lupin came hurtling into the room, his face bloodless, his wand raised and ready. His eyes flickered over Ron, lying on the bed, over Hermione cowering next to the door, to Calleigh heaving on the floor, to Harry standing over Sirius and Calleigh, and finally to Sirius bleeding next to Calleigh comforting her.
"Expelliarmus!" Lupin shouted.
Harry's wand flew once more out of his hand; so did the two Hermione was holding. Lupin caught them all deftly, then moved into the room, staring at Sirius, who was still comforting Calleigh who had stopped heaving.
Harry stood there, feeling suddenly empty. He hadn't done it, and he had had the perfect chances. His nerve had failed him. Sirius was going to be handed back to the dementors.
Then Lupin spoke in a very tense voice, "Where is he, Sirius?"
