She didn't wait.
The moment Remus told her where he was, she ran. She didn't ask permission - she didn't have time. It didn't matter that she had a pile of homework, essays, and tests due that week. She just went.
Only when she reached St. Mungo's did everything actually set in. First, she had no clue where to find James. Then, when she finally found the room, she didn't have the guts to go in. As a result, she stood and waited outside the door. After a while, Sirius joined her in the hall. Sirius' eyes, usually so relaxed and youthful, were hardened and lost. He immediately hugged her.
"It's going to mean a lot to him that you're here," Sirius swallowed, and his voice cracked.
"Is she?"
"Not yet," Sirius shook his head. "It should just be the two of them in the room," he explained sullenly, referencing James and his father.
"Do you need anything?" Lily asked quietly.
"Just be there for James. He's going to need you." Sirius hugged her one last time and left. It was obviously that he was fighting the urge to cry and didn't want to break down in front of her.
Three hours later, James finally emerged from the room. When his hazel eyes set on Lily Evans, he looked relieved.
"Is she?" Lily bit her lip, nervously playing with her fingers.
James sighed and nodded. He looked so worn out - deep bags lined his pale face and while his eyes were dry, they were red from crying.
Lily didn't hesitate. She instinctively reached her arms around his and wrapped him in a hug. Her eyes filled with tears, and she was glad to have her face hidden in his sweater. She felt him shake some and knew from experience that his emotional intakes of air were painful. They broke apart only when an exact replica of James sixty years older patted him on the back.
When James let her go, she couldn't stand not being close to him, and she instantly reached for his hand. She wouldn't let it go until seven the following morning, when they finally fell asleep.
