Often, they stick around just long enough to receive a good punch in the nose. Such is the case of Nervus Illnus, whose breakdowns chariot is stolen by Asterix and Obelix as they dash towards Camaracum (Cambrai) and its famous humbugs. Other Romans, however, are more tenacious and put up a good fight before succumbing.
Like Spongefingus who, after having been «helped» by our Gauls as they use him to help get them past the roadblock set up by Fishfingus, is left along the side of the road. Unrelenting, Spongefingus tracks our heroes to Durocortorum (Rheims) where he puts on a show as fearsome as a creature from «The Shining» and threatens to put his pilum in their sternum. (You'll note René Goscinny's talent at bringing a «dead» language back to life!). Asterix quickly calms this hothead by uncorking a bottle of Durocortorum wine (otherwise known as Champagne) in his face.
