Right, the paperclips. Castiel watched as Orihara moved toward the desk that held them, taking a moment to glance around the room and make certain that there were no dangers. It seemed to be clear, but he couldn't help but get the feeling that it hadn't been so earlier in the night. His senses were too dulled to know more than that, but it would be wise to take care while here.

As he moved closer to the human, he took in his question and then shook his head. "I've never had reason to before this point," he said, hoping that Orihara wouldn't want a more detailed explanation than that.

Granted, the young man already knew about how Castiel could move around. He could likely deduce on his own why he'd never needed to pick a lock until now.

"I wonder if it would be possible to find better tools in the future," he commented as he glanced down at the paperclips.
