Despite the Star Wars universe's predilection for metric measurement, Obi-Wan Kenobi uses "miles" in describing the extent of the Geonosian catacombs.

Though the expanded universe has offered a possible explanation for Poggle the Lesser's diminutive title, this episode contrasts it with Queen Karina's label of "the Great."

The script originally had Luminara impale a Geonosian on a broken stalactite to introduce the idea of them being undead. In the finished episode, it's a meaty punch to a bug's midsection that clues her in.

Though developed completely independently, this is the second zombie story in Star Wars this year. The first was the adult horror novel, Death Troopers, released by Del Rey in October.

Luminara now has her correct lightsaber in these Geonosian episodes. In her appearance in season one's "Cloak of Darkness," the rushed production schedule forced the crew to have her use Plo Koon's lightsaber instead. However, their weapons are nearly identical, save for the gold plating Luminara's handle has at the bottom end.
