"I've been using Bella for messages. It seems a lot quicker, but unfortunately the bus won't let me take her on some of our stops. That's why I've started using the cell." It'd been so long since he'd worked with Theo on something that he couldn't stop himself "But let's find a way to make it run on magic, although we might have to figure out the bus. It's an entire system it uses to connect us." Draco nodded. "I think so, because the events were the same, but the person wasn't you. The more we talked, the more convinced I was that something had gone wrong with you and I didn't know what. Now I know."
The fact that they would be answering with the truth is exactly why the answer worked. "I know that you have never been here, and so many are Gryffindors that the truth will be all you need. And, exactly! I won't live like that again."
Draco put an arm around Theo. "Let's go to my room. Let's start with that, and then we can move to the phone." While sitting in his comfortable living room.
