"Why have you hidden a knife under your pillow?"

Sirius asked you as he chew on his food and Fred and George looked at you.

"Huh? What?"

You asked as you look at your father.

"There was a knife under your pillow, you know about this, what was it doing there?"

Your father asked you as you gulp.

"Nothing.."

You mumble as he raise a brow, everyone looking.

"What do you mean, nothing?"

Sirius asked suspiciously.

"It's just there in case.."

You said in a whisper as you look down at your plate.

"In case of what? what are you talking about?"

Sirius asked you as he out his fork down, staring at you, everyone were eating and looking a you.

"I don’t know.. If there’s was a break-in.. or..-"

You said but got cut off by your father who clasped his hands together on the table.

"Show me your arms."

Sirius demanded as your eyes widen, the others look at you both, Fred and George was staring at you worried and concerned right now..
