“Why don’t you pull out that little map of yours and ask it?” Snape said, his lip curling.
James gulped. Did he really know about their map? How did he know?
“JUST TELL US!” Sirius yelled, angrily to him.
Snape smiled and turned on his heel, heading off towards the dungeons.
“OHH THAT PRAT! THAT SODDING GIT!” Sirius was yelling. He was really angry.

“What is it?” Lily asked, running towards them. “Oh, Peter, what happened? What is it?” she asked him, embracing him.
Sirius shook his head, “He won’t tell us anything. But it’s something to do with Snape.”
