They watch him as he watches them, back ramrod-straight, hands folded neatly in their lap, eyes boring into his silhouette. Their cohorts are observant and to claim otherwise would be a disservice to the pair of them, but they are trusting - entirely too trusting, to a very particular fault.

It does not do to grow complacent as one is being watched.

Assuming he does not speak first, they will do so in his stead:

"Have you something to say, Mr. Shiro?"
