"It's not you, Gin, it's just--work. This is my job, too." Charlie scowled and Mircea woofed at him, or more likely the tone of his voice. That brought a reflective smile to Charlie's face and he sat down beside Ginny on the cot, close enough for her to touch if she wanted but not requiring her to. "One of our people did something that weakened it, and we're not quite sure how yet. Then we dropped it with Patronuses. And yeah, it scares me, because who knows who set this up, or if it's left from the war, and how do we keep another one of these things from going off? But that's tomorrow's worry--today I'm just glad you're alive."
He had to think for a minute before answering about Bill. The substance was easy, but putting it in words was hard. "It's always okay if you want to visit Bill. It's always been okay. I know you can't face Bill--or Mum--right now, but the Burrow is your home too. When you're ready, come visit, and I'll smooth things with Mum and Bill."
