broadcasting into a headset that goes nowhere
Troeltsch sat up against his locker near Wayne, wearing a disconnected headset and broadcasting his own match in advance.
Context
The pre-match room's emblem of transmission with the receiver unplugged: Troeltsch narrating a match that hasn't happened into a headset wired to nothing, an announcer who is his own and only audience. The address is complete and the circuit is open at exactly one end, which is the whole theme rendered as a boy talking sportscaster-patter into dead foam.
