Actually if Cho was feeling anything today it was guilt. Guilt for all the times she'd wished Harry was dead instead instead of Cedric. "You know exactly what I meant," her voice was quite snippy at this point in time as she knew they'd had this conversation before. True, several people in their world had scars from the war, but the scars surrounding Cedric were different. Cedric's death had been brushed under the carpet by the Ministry as just an unfortunate event instead of being recognized for what it truly was.
The fact that Zacharias mentioned his destination proved that even though his words might be harsh he actually did want her around. The mention of food reminded Cho that she'd not had more than a passing bite all day. Luckily she had thought to swing by Gringotts and exchange a few Galleons in anticipation of jumping in and out of Muggle areas today. "I suppose I ought to make sure you don't encounter any problems on your walk."
