When Lucas reached the floor where both the sixth and the tenth Grim were locked in their own separate rooms, he first went to meet Greed who had been caught and imprisoned in the mansion so that he wouldn't cause any harm to Belle.
"If you didn't want me to notice you, you shouldn't have come to meet me," stated Greed who had taken himself to sit on the edge of the window with one leg that was pulled up and another that rested on the ground.
"I wouldn't be able to question you then," said Lucas, pulling out some sticks from his coat to hand it over to Greed, "Hungry?" he asked, waving them.
