The boy
Danny walked across the room and lowered the shade... By the time he turned again, the boy was fast asleep...
He went back to his room and closed the door without locking it. He sat on the bed, looking at the empty dropper. It was getting dark outside... 

Danny
Numbly, he took the needle off the dropper and wrapped it in a piece of paper. Then he wrapped the needle and the dropper together... 

"Gotta stash this someplace," Danny thought.
