Zacharias took the offered hand, and shook it. He and Goyle had never been friends back in the school days but, well, things could change, couldn't they? Theodore was important to Greg, clearly, and a friend of his, so they would become acquianted, at least.
"He deserved it?" Zacharias guessed in an equally quiet voice when presented with the news that Theodore had killed his father. Because he just didn't see Theo killing someone for no reason.
"It's no wonder he couldn't cope, not in Mungo's," he said. Theodore had seemed scared witless, and how could anyone cope when they were frightened?
"I can go see him." No need to make him less comfortable. He drifted across the room - glancing about as he did - and opened the door to the bedroom. Where he found a lump of blankets and a softly singing Theo. "Theodore?" he said quietly. "It's me. Zacharias."
