"You aren't as human as you thought, Jackie Boy," A deep booming voice seemed to echo through the alley. Edward drew his wand, knowing James was using a spell to make his voice to seem like it was coming from everywhere. The next thing they heard was the evil laughter of an enormous man, and it echoed and swirled all around them. Angus found himself stepping a bit closer towards Jack, expecting an attack and feeling the need to ready for it.
Then Edward heard strong bootsteps. On the rooftop, Edward could see the silhouette of one of the biggest werewolves he'd ever seen in his life. He was partly transformed, Edward saw. Transformed almost entirely but just restrained enough to be able to speak.
"You're more beast than human, Jackie Boy," James laughed. "You work so hard to fit in with those pitiful humans you've dedicated yourself to. But consider this. You might see them as your children, but its crossed your mind that they're your cubs. That's not a human thought, Jack. Werewolf. You've seen them as your pack. That's not something a human father thinks of his children either. Werewolf. And don't think I didn't hear that growling. I have excellent hearing. Werewolf, Jack. When was the last time you heard your mighty mentor, Lupin, growl? Or his son in law? Or even the legendary Donohue you have with you? When have you ever heard them growl because they were unhappy?
"You're a pitiful excuse for a werewolf, and not much of a man either. You don't know what you are or what you want to be. Do yourself a favor. Pick one. If you want to be a werewolf, then stop denying what you already are. If you want to try to pass as a human, then stop acting like its alright to act like an animal.
"You know why I did this? Because I can," he said simply. "That's all. And if I want to do it again, I will. I don't have any interest in keeping them--this time. If that changes, I'll take them again." He made a slight hand motion.
Angus had spun behind him and saw two werewolves in the shadows behind them were now holding the children. They let go of them, and the kids stood, frozen. Angus motioned to them, and they ran to him because he was closer to them than Jack. They clung to his legs. He crouched and hugged them, and made sure they were indeed unharmed. He picked them up.
"Jack," Angus said quietly. "I have them. They're fine."
