Fred made a "hmm" sound, thinking. "Don't people from your time have summer dresses? That are just a light material?" Yes, Fred had gone to the library and attempted to find something about the culture Helena was used to. He had only been able to stomach being in the library for an hour though so he hadn't soaked up much.
Fred looked behind them and realized people were forming a line behind them, so he touched Helena's elbow lightly and led her to a chair with a blue balloon on the the back of it. The irony of sitting a Ravenclaw at a blue chair wasn't lost on him and he chuckled a bit before sitting down in the chair next to her. "The people behind us looked a bit peeved."
