Firo, who had fancied himself rather clever just then, droops a little to see that expression. Aren't they in this together?

But it's not a no, and that's good. Firo turns and follows right at Roland's side.

He doesn't share Roland's instincts for acting, but it helps that he still has no idea what Roland's goals or plans are. He automatically wears one of his usual faces of wide-eyed blankness. Look at this dolt. Better he and his lanky friend get stuck on this waste of a job than an actual valuable Capitol soldier, right?

The guard surveys them both, making a big deal of it as if it's his sacred duty to be sure that inferior soldiers not be given a pass--with the implication that these two may be of dubious quality. But good enough. Eventually, he shrugs and nods. "Don't break anything."
