"Yeah, you and Dumbledore went off your own at the end of sixth year and how'd that turn out?" Ron asked sarcastically. Harry might not have told them everything about what happened, and Ron wasn't always the brightest bulb, but he wasn't stupid. He knew something was wrong with their former Headmaster. He just wasn't sure how serious it was. Serious enough that Ron wasn't reassured by the idea of Dumbledore being his back up.

No, you're doing this because you think you're meant to. Just like we are. And no, you wanker, you don't get a say. We're going to be right there by you, and I'll punch you for real if you keep talking about this," he nearly shouted.
