There is one interesting scene of triumph repeated in both The Trial and The Castle.
K., in an altercation with a hostile bureaucrat, reaches out and grabs his notebook/document bag and keeps it away like a middle school bully, a symbolic act of castration and dominance. When he scornfully tosses it back, the bureaucrat pathetically clings to it like a child given his blankie while K. proudly towers over his cowed adversary.
But it's not a real victory.
