[Sharak huffs in frustration.] We already have a better lead on the circles than on the organisation. Whatever they're for, we need to find the rest of them as well.

[If nothing else, they're dangerous to bystanders. Even if they don't lead them directly to the culprits, finding other circles and comparing them could give them more information which they desperately need.]

We can't ignore that "organisation", if that's what they are, of course, but if they keep to their current pattern... We can keep an eye out for them when newcomers are due to arrive. Today seems pretty quiet, but they'll be due again within the next few rounds.
