The kiss was a welcomed surprise that was cut short by Ron's smartarsed comment. Ginny shot her brother a vaguely threatening glare over her shoulder, before turning back to smile and then immediately frown at Neville.
"What happened to your head?" She asked, stepping aside to let Neville into the house. "And I thought your parents were coming with you?" She'd hoped that her parents would be sufficiently distracted by the Longbottoms and vice-versa, meaning that she and Neville would only have to worry about Ron and twins, really. Bill and Charlie were much more likely to be allies than to cause trouble. She was counting on them.
Not that she expected things to explode at some point during the day. It just was better to be prepared for these sorts of things.
