At the end of his tale, the Pardoner encourages the other pilgrims to come forward to make offerings to his relics or purchase one of his pardons. He tells them how lucky and honored they are to have a pardoner with them on their journey. Who knows, someone could very well fall off his horse and break his neck, in which case the Pardoner can absolve him of his sins before his soul leaves his body.
The Pardoner seems to have forgotten that he's just tipped his hand to the pilgrims in the Prologue to his tale – he's confessed that his relics are totally fake and that he doesn't give a hoot about the salvation of people's souls: his "entente is nat but for to wynne / and no thyng for correccioun of synne" (117 – 118). It would take a pretty dense pilgrim to give the Pardoner any money at this point, right? Well, maybe not.
The Pardoner's hard sell at the end of his tale might tell us that he's familiar with the idea about the separation between the holiness of the actor and his action. On the other hand, it could just indicate that the Pardoner has forgotten what he's already told his audience about himself. After all, the Pardoner insists on telling his tale only after he's had a drink (or two) at a nearby "alestake" (Pardoner's Introduction 36). Who knows how much he's had to drink at this point?
And finally, with this ending, the Pardoner continues a pattern of slipping between two audiences: the pilgrims present here and now, and the people to whom he preaches as part of his trade. At the end of his tale, he seems to have blended the two audiences into one in his mind, so that the pilgrims present here and now have become the people to whom the Pardoner preaches as part of his trade.
