He pulled the lever, and the elevator descend into the dark depths.

The sharp sound of scraping metal followed them down, and sparks flew out from the corners of the elevator. The faint flashes of light illuminated the young man's profile. His silhouette looked rather gloomy.

"Then I can't thank you enough."

The researcher cheered up at this news. If he hadn't been so awed at the sound of the young man's voice, he would have already grabbed his hand and begun chattering on about every single potential research project.
