Harry had arrived home from Auror training both depressed and worried. Ron had disappeared halfway through the morning, and not responded to his owl. He bit his lip, hoping that everything was all right. Not that he'd blame Ron at all if he up and left. Everyone was mad at them, and it was Ron's family. Definitely more important than Harry.
"Ron?" he called out as he entered the kitchen. "Ron are you home?" There was no answer. He called for Kreacher, before remember that the little had gone to Hogwarts to visit his friends and wouldn't be home until after Halloween.
He noticed a pile of ashes on the table, and winced. Those were definitely Howler ashes, and could be from any number of people. He quickly went through the house, stomach feeling absolutely horrible when it was revealed that Ron was no where to be found. He flooed Hermione to see if she'd seen him, but she wasn't home. And he didn't feel right flooing Ginny, or even George. They definitely wouldn't want to talk to him, and he didn't blame them at all.
He returned to the kitchen and sank into a chair, wondering where Ron was, and why he hadn't left a note.
