Ginny didn't love seeing her brother this way, but he certainly didn't need to apologise. She understood what he was feeling, because she felt it to. They'd never really talked about what had happened to Fred, but that wasn't good for either of them. Keeping it bottled up meant she hadn't really dealt with things herself. It was part of what had led to her fighting with Harry so much. Even knowing that didn't make it easier for Ginny to let herself truly mourn. Instead, she let it all built up until her temper just exploded over the stupidest things.
"It's okay," she reassured her brother as she held him tightly. She couldn't seem to hold back her own tears anymore and a few spilled into her cheeks. Maybe that was a good thing, though. Keeping it all in wasn't healthy and if there was anyone she could let go in front if like this, it should be Ron. She didn't like looking weak in front of him. Ron treated her like a baby enough as it was. Grieving together was something they needed, though. Some part of her knew that.
