Orcu-san and Mercenary-Domo are both, "Do we need to call somebody about that hit-and-run?"
I can see in the next panel, both the surviving orcs and mercenaries are exchanging insurance and license/registration/contact information while they contact the gendarmes about the "vehicular assault and batter/vehicular homicide".
I think the comic artist/author missed out on a potential for "mobile communication devices" and having both the orc and humanoid mercenaries contacting the Duke's "guards" to report "an illegal hit-and-run with magical carriage."
