There was no one at the vets because she hadn't gone in. In fact when there was a knock at the door, it caused Luna a bit of a fright because she was completely not thinking about anything else. Like the fact that someone might come to check on her. Truth be told, she was in a bit of a daze. Once her heart stopped pounding, she went to open the door and figure out who was there. Maybe it was the people from St. Mungos and they had forgotten something.
When she saw that it was Rolf, she couldn't help but look a little confused. It was clear that she was kind of out of it. She was pale and had clearly been crying and truth be told she was just kind of staring at him for a moment as if she had no idea why he might be standing there in front of her.
Earlier in the morning when Luna had gotten up, she had discovered the worst. Her father had passed away in the night. She hadn't been there holding his hand, like she had promised. Since discovering him, she hadn't been feeling much of anything. Like she was numb and clearly her body was in autopilot. Even when they had come to take him to the funeral home, she hadn't said much of anything. So there she was, staring at Rolf.
