Walter has to just... set the spoon down and look blankly at her for a moment, trying really hard to keep his shit together. It mostly just translates to his shoulders shaking a little from the laughter he's not letting happen. "Thanks. I did just go to all that trouble to fix my reputation and all."

And then she asks and he regrets. The frown is enough that he quickly shifts his gaze away. My, look at this stew. He'll just get to eating that now. "You don't."
