Danny showed up at Belle's door, and seriously considered turning right back around. he didn't usually talk to people, much less venture out in the port keys and go visiting strangers. But Belle had captured his interest, and he was desperate for companionship.

He raised the cane to knock, then let it fall back to his hand, and rapped on Belle's door with his other fist.
