Inque proves to be the new Batman's most persistent enemy, confronting him more often than Derek Powers as Blight.
Inque seems to know where the entrance to the batcave is, as Terry prepares for her possible return in Disappearing Inque (1999), although Bruce mentions in that episode how it was dark and the batmobile goes very fast, Inque might still have seen how the cave is beneath Wayne Manor one of the most established estates in Gotham City, however she doesn't appear to make the connection between Batman and Bruce Wayne.
First episode to show the older version of Barbara Gordon aka Batgirl.
In the Batcave there are several displays of Batman's rogues including The Riddler, Harley Quinn, Mad Hatter, The Penguin, Catwoman, Firefly, Scarface, and Mr. Freeze's freeze gun, theres also a display of the Gray Ghost Bruce's old childhood hero, when Bruce is putting the cowl away at the beginning of Rebirth: Part 1 (1999) the cases are much smaller with the costumes folded up inside and sitting on rock stands.
This episode won an Annie Award for Outstanding Individual Achievement for Storyboarding in an Animated Television Production.
