Adrian and Tony
Tony had not had anything in mind from the second he saw the mark aside from the fact that his son was somewhere and he needed to be assured that he was safe. Words in a journal were not enough. Someone could fake that with a stolen journal easily. As soon as he got a reply to his note he headed out from the room he was checking and hurried to the Great Hall.
There was a massive flood of students there and he took a few minutes to find Adrian, but the moment he did he felt a twinge of relief. On the pretence of checking in with a number of students he made his way over, clearly taking a few extra seconds to ensure that Adrian wasn't hurt in any way before he spoke, his voice low. "It's good to see you're safe."
