There's got to be more to this story. Why did he keep the leaf?
Nathan bit his tongue, doing the only thing he could think of to stop himself from scolding him. He's just a kid, he reminded himself. And he kept the leaf. He didn't sell it. I just need to listen and hear the rest of the story...
"So, I went down to the pawn shop," Avery continued, seemingly unaware of Nathan's disapproval. "And I asked the owner how much I could get for it. Heh, you wouldn't believe what he told me."
Gabriel visibly stiffened, taking a few more steps away from them. "I have to leave," he said quietly, dissolving away without explanation. Avery chuckled, oblivious.
"He told me he'd give me sixty dollars for it. Sixty! That's not even half of what it could be worth!"
"I'm sure there are other factors you aren't considering there, Avery," Nathan said, staring at the spot where the angel had once been, not liking his reaction. "They have to make a profit too..."
"So do I!" the teen snapped, then stopped, taking a deep breath, his head still lowered. "So do I... I burst out like that while I was there too." He ran his hand through his hair again, sounding much more like himself than he had a moment ago. He was quiet for a long time before he spoke again. "Nathan, I learned two very important things today. First, this." He held up the golden trinket, the metallic sheen fading away as it became a dead leaf once again. "Seems I can reverse my powers too."
Nathan tried to give him a smile, relieved that he had calmed down some. "That's convenient. I guess if there's an accident..."
Any relief he'd had vanished with those two simple words. He had a dreadful feeling he knew exactly where this was leading. "You...?"
"Yeah," Avery said softly. "I... I was just trying to get the leaf back from him, I swear! B-but I touched his hand, and... and..." His shoulders began to shake, tears falling onto his jeans as they rolled down his cheeks. "I tried to stop it, but I couldn't. I couldn't stop it... It all happened so fast..."
Nathan didn't bother waiting for him to say it, taking him by the shoulders and pulling him to his feet as he stood. "We need to get inside. If Micah finds out..."
"If Micah finds out?" Avery finally looked up at him, even as he tried to pull away. "Nathan, I killed someone! You heard him when he made that deal: if I become a threat... if I become a m-monster..." He shook his head. "Nathan, look at me!"
He had been trying not to. As soon as the teen had looked at him, he saw the change. Maybe they could have made a plea for him if it had just been the accident... but it was an accident caused by an act of greed. Even if that could be ignored, there was no denying the physical change Nathan saw: the brown irises of Avery's eyes had nearly doubled in size, and as if that weren't enough, his pupils had turned into sideways slits. The poor teen sobbed. "What's happening to me?"
"We need to get inside," Nathan said again, trying to remain calm, trying to keep him calm, desperate to get Avery out of sight. But he continued to fight him, eventually tugging himself away.
"No!" he screamed, covering his face. "Holy shit, Nathan. Micah knows I'm staying with you! As soon as he finds out what happened, that... that I..."
"Who says he has to know?" Nathan asked, his voice cracking, trying to get through to Avery. "He didn't show up right away, right? He doesn't know. He doesn't have to know. We... we can figure this out..."
"FIGURE WHAT OUT!?" Avery staggered backwards, wrapping his arms around himself. "I'm becoming a monster, Nathan! I... I can't stay here. I have to hide... somewhere else..." He took more steps back. "I'm sorry, I'm sorry..."
He looks like he could bolt at any second, and if he does there's no way I can help him. Maybe I can convince him to go with me to Alton's. Maybe he can do something. Where the hell did Gabriel go? Shit, what if Micah does know? It really wouldn't be safe for Avery here. What do I do? What do I do?
