what effect does archie have on frankie rollo?

Effect as in the fact that he's hit by the Virgils and then carried away? Frankie wasn't afraid to challenge the group, and that is why they chose him. As far as Archie goes...... he's put on the spot in this chapter. He questions Frankie like Pilate questioned Jesus, and in the end he receives very similar answers. I don't think that Archie has an affect on Frankie, rather it's the other way around.
