Octagon Vreedle, Argit and others in “The Enemy of My Enemy”

A Plumbers' academy strikes one as a somewhat improbable place to find an intergalactic reprobate such as yourself.

Keep it down, will ya? You guys aren't exactly model citizens.

Are too. Octagon and me are what y'all call "probational cadets."

We're attempting to what you might call improve ourselves, and make our daddy proud... so he doesn't have us whacked.

Again.
