Ginny had gone through scarier things. She had been possessed by Voldemort. She had seen death and she had argued to fight in a war and did. However, she could feel a low, increasing beat behind her ribs, simultaneously beating against her voicebox. She didn't notice it until she thought about speaking, but remember she probably shouldn't and also didn't have much to say. She watched with pensive eyes as her brother congratulated Harry and Daphne. Ginny has had a hard time decoding her emotions since the war, mostly because she had been taking the time to actually pull back and decipher things before doing them. However, she had promised her mother she would behave and so she watched for the most part.
A loose smile fell on her lips as George and Harry interacted - nostalgia was almost necessary at any sort of event involving the Weasleys -, she wasn't going to retreat at any point in this. She wasn't cowardly, but she wasn't sure how to balance herself and overt politeness at the same time, especially when dealing with people nearer her age, who she had always striven to treat as equals, which meant being honest with them. And honestly, she could have had many things to say. Ginny did not say anything. That is, until she was greeted. Ginny hadn't frozen, if anything, she warmed up. She had acquired from Ron, she small ability to turn her ears red at inconvenient times. It was barely noticeable, and she had barely felt it until she spoke. Ginny unknowingly avoided Daphne, but couldn't help but force herself into obvious support.
Ginny stepped in front of George and pulled Harry into a hug by his neck, despite his other hand being preoccupied, she didn't notice. She let go and shrugged somewhat tenderly, "Yes, well, our other plans fell through, so we showed up." Stepping back, she blinked at him. She would have said congratulations, but she figured it was implied, cliche, or would come up in later conversation.
