Sometimes Lucciola has dreams where Dio is trapped on the moon and he climbs a tall, tall ladder to reach him. His hands are cold and slick, his body exhausted, but the thought of Dio keeps him moving, one hand over another until finally there is nothing left but a cool, grey, alien landscape and a much closer horizon than he's used to. That, and Dio waiting for him.
"I knew you'd come," Dio says, and in the dream he smiles.
