Crowley had been moved to applaud, but only two claps came out before he paused and cocked his head in curiosity. It was that girl, Elle. Talking to herself. Unless of course she had been talking to someone on the phone, but the phone had been gloriously destroyed and so she couldn't possibly be still talking to someone on the phone.
Which left talking to herself. This girl had issues, apparently, and Crowley would have turned and moved the other way if he hadn't been so intrigued as to what caused her to react in such a way. Curiosity may have killed the cat, but it also damned the demon. So, let him be damned.
"Something amiss, Elle?" He asked, looking down as she bent to pick up the pieces. He couldn't hear what she was saying, but saw her lips moving.
A piece of the phone had flown over toward his feet when she had zapped it with her electricity. A display he had enjoyed immensely. Whatever Elle was, Crowley appreciated her talents. He bent to pick up the piece by his foot, stepped closer to the girl and extended his hand with the piece in it to her.
Why was he being nice to her? What he should have done, what any good demon would have done, would have been to make it harder for her to pick up the pieces, not help her. He wasn't entirely sure, but decided it was better to act on his instincts than to not. Instinct told him to help. Maybe she'd be useful to him.
