Ginny didn't hear the commotion going on, but noticed when Ron came back looking a little off for someone who just went to the bar.
"So, finish your drink already?" She inquired an amused smile on her face.
Maybe this thing was bother Ron as bad as it had been bothering her. She couldn't blame him for having a quick drink... it was time to be happy and amused, not confused and feeling like you were cracking up to be a nutter.
