Riding the Action Gravy train

I'm pretty excited that we (by which I mean, PJ) met the Monday deadline for this latest strip.

As to the origins of this mysterious new gravy hero... I imagine we'll be coming back to it at some point. Rest assured: Gravy doesn't just happen. If it did, you might live in a world of gravy waterfalls and gravy meadows where unicorns feast upon their choice of brown or cream-colored nourishment.

I just completely lost my train of thought.
