The shuttle that Admiral Perry uses to transport the device to the Krill bears the registry "ECV-197-1". This is the registry of one of the shuttles assigned to the Orville, which is seen later in the episode still aboard the Orville (shuttles are given the registry number of their parent ship with a numerical suffix to distinguish them). The model for the Orville's shuttle was reused without alteration to represent the admiral's craft.
There is a gnat flying around the Krill's head in the cell at 71:20.
