Allusions

 * Reference is made to Clark Kent in this episode. Clark Kent is the human identity of Kal-El, aka Superman, who is Kara's cousin. On Supergirl, Superman is played by actor Tyler Hoechlin and appeared last in "Nevertheless, She Persisted". In this episode, Kara is prepared to use her body as a whirling drill and notes that she saw Clark do it once. This is a wink to the 1978 feature film Superman: The Movie where Superman spun his body around at super-speed to drill himself through a concrete sidewalk.
