Sure it does -- a reference to bat "radar" (actually sonar).
It looks like the "bat-cam" links to Vinnie give Ansom a bit more intelligence (in the military sense of "information") than Parson thinks he has. Whether that will make any difference, given that Ansom is off-turn, remains to be seen. It might enable them to pin down the location and configuration of the "party platter" dwagon formation.
Ansom might have a major problem holding his coalition together, especially if his original plan of a quick brute-force push through the walls is no longer an option, and they have to either sit down for a long siege (would that even work in a world where cities produce resources, or does a siege interfere with a city's functioning in Erfworld mechanics?) or go through the tunnels (into some nasty traps, possibly taking heavy losses for no perceivable gains for their first attempt... and second attempt... and third attempt...).I'm gonna love to see the aftermath of this as Ansom craps his pants at how effective the counterattack was.
