Harry saw Ginny through the invisibility was with her family and Fred's corpse. He was lying on the ground, with blood all over his hair.
Molly was on her knees, having long sobs that didn't seem it would stop. Arthur was on her side, crying as well, but only tears sliding on his cheeks. George was on the side, alone from his family, all crumpled together, his arms around his knees, as though to protect himself from cold. It was so desperately sad, a war for one Weasley-less world.
He watched Ginny, standing up, hugging Bill, with Fleur at his side, holding his waist. She seemed- and was so strong. But she needed him as much as he needed her. He took off his cloak and walked slowly to her. She saw him out of the corner of her eyes and turned around. Ginny smiled sadly.
She managed to walk the last few steps before he enclosed his arms on her. He held her with a strong grip, overwhelmed by the feeling of her known body in his arms. Her smell invaded all his senses and he held on to her as if she was his rock. They stayed there for a long time, trying to take in everything that had happened since they last met.
When they released their grip, the sky was dark. They entered the Great Hall, holding hands. They saw families together, mothers watching their dead sons and daughters, the mess that had become Hogwarts.
Instinctively, they went up the stairs to the Griffindor common room. Most of it was intact, although some tapestries were ripped and tables broken.
They found a sofa and sat there. The silence was overwhelming : "Never leave me again" said quietly Ginny. Harry responded in a whisper : "Never". They laid their back against the sofa and let go. Sleep was all that mattered now. They were safe. Home.
