Atticus looked up to see the frantic parents of the boy outside the door. It seemed like the mother would knock the door down at any moment. Atticus nodded at Robert's orders. "Right." he said and he quickly walked out the door to try and calm the parents. He turned himself around as he exited the room, and with his wand in a position that the parents wouldn't be able to see it, he cast the nonverbal spell.
Porto Sisto.
As soon as he turned back around, he was almost attacked by the mother asking about what had happened. How and where her son was and Atticus just stared at her for a moment. "Ma'am calm down please. You're son is fine. He merely splinched himself." he tried to explain to the woman. The woman didn't seem like she was calming down at what he was saying and Atticus had one of the nearby nurses bring her a cup of chamomile tea. "Robert Lupin will be out here shortly to tell you how your son is." he told them.
"I want to see my son now. Let us through!" the woman demanded. Atticus shook his head at her. "I'm sorry I can't. I'm under orders to not let you in." he said.
