Orion Black's preferred method of punishment was silence. Where Walburga would shout and shriek and break things and possibly even break her sons if they didn't move quickly enough (Sirius sometimes didn't — he would get too caught up in shouting back at her), Orion would summon them to his study.
He would sit, and he would wait.
Sirius would glare at Orion defiantly, chin raised and eyes blazing. Regulus would look down at his feet, not daring to meet his father's eyes, and wish he could sink into the plush green carpet and never have to face the silence again.
