Charlie glanced up with concern when Theo's breath started coming shorter. He didn't ask him to stop and it was important that his feet were cleaned and healed as well as possible before he went home. He didn't hear the first murmur but the second one registered thanks to the distress and he snatched his hands away, jerking back. His mouth also opened in surprise and his wand clattered to the floor. It went unheeded though as Charlie tried to move back slightly and make sure he wasn't touching Theo. Whatever those words meant to him he could tell it wasn't good.
"Theo," he said softly, having no real clue how to help.
