"Hermione," Harry breathed, much softer than Ron's exclamation, but no less relieved. He moved to the other side of her bed, hesitantly reaching out to touch her hand. He didn't want to interfere on the moment she was having with Ron, but he also didn't want to make her go one more moment thinking he was dead. "I'm here, I'm alive. And I'm sorry."
Probably best to get that out of the way. He had a feeling he was going to be apologizing a lot, in the next few days.
