Bases Loaded Walk Ends Game (or does it?)

[jmkupka]

Before you can leave (at your normal pace), DC brings it to your attention, at a volume only you can hear, so you can't continue your exit.

You can't rule her out (didn't enter DBT); most likely the teams will line up for handshakes after the celebration at the plate.

What can DC do besides tell defense to not leave their positions, and hope offense ends their celebration and enters the dugout?
