text: Epiphany When Yossarian starts to convince Aarfy that he will have to pay for the rape and murder of Michaela, for the first time in the novel he loses his composure and shows fear.  His fear is not realized, though, as when the police arrive, they instead arrest Yossarian for going AWOL and not Aarfy. His reprehensible actions are therefore vindicated and he can be satisfied that the system is there to protect him.
  Biographical summary
  Actions in "Catch-22"
  On mission
  During dangerous missions Yossarian always shouts at Aarfy to get out of the way so he can get to the escape hatch. Aarfy always replies that he can not hear him, infuriating Yossarian even more, and no matter how loud Yossarian shouts, Aarfy never can hear him (except when he says "never mind"). On one mission Yossarian gets so upset he punches Aarfy, but to no effect as his body fat absorbs all the blows. Yossarian's frustration with Aarfy is never vented and he always gives up, leaving Aarfy to carry on regardless.
  He nearly gets himself and his comrades killed several times while getting lost on mission:
  Over Ferrara, when Yossarian went round a second time to bomb the bridge and Kraft and his plane's crew were killed.
  On a milk run to Parma, where Aarfy led the planes over the city of Livorno and Yossarian got hit in the leg by flak.
  With Colonel Cathcart, where the plane almost got shot down.
  Aarfy is so heedless of his own personal safety and the well-being of others that it always astounds him when they become angry at him.
