Hermione thought she'd be able to keep a strong face as Ginny came in, but the moment she saw her she was already going in to hug her, and she clung a few minutes longer than the old Hermione - the Hermione who went to school, who cared about grades and prefect duties and Hogsmead visits - ever would have. She had the horrible suspicious that she was going to cry, and had to push that away before she could really let her go, then she cleared her throat and sat down on a box of supplies that was there by the tunnel.
"I had to warn you about what's going to happen." She said finally.
