"See, it's a date then. All significant others included," and Ron grinned again, "And of course, Harry, for the sake of your precious hide, I wouldn't dream of Slytherin-bashing. My mum would have my own hide, for being a bad host if I did that. Now, I guess I'll have to see if I can get Ana to make it as well."
As he said her name, his demeanor changed. He wasn't as jovial, and he looked more puzzled. He felt awkward about her, and wasn't sure how much he should say. Finally, he said, "I...I just don't know her that well."
He fell silent, and took another bite of his subject, his high at being next to his favorite girl fizzling away. He gave Hermione a half smile, and then looked over at Harry, not sure what to say next. He thought about the flat, and perked up slightly, "The patio upstairs is coming along. I still need to get Neville's advice. It would be great for you to see it."
He went back to eating, not sure what else to say.
