Spy three suspicious butterflies flitting over hedge. Check the planes. Yep, small foliots, arms flapping wildly. Wasp rises up behind them, shoots down out of sun, zaps them with Infernos, one, two, three. Burning butterflies crash-land in pond. Alert master to my triumph. She inspects charred fragments. Her scowl deepens; turns out they were her slaves, returning with valuable information.
