 * This is the first episode where the character of Iris West-Allen does not appear.
 * Allegra Garcia does not appear but her doppelgänger did.
 * Cisco relates multiple psyches in a single brain as "Tyler Durden times 1000", referencing the split personality of the protagonist of the Fight Club film. Thawne overhears and was about to quote the first rule of Fight Club, before being cut off.
 * The color red is the third color used for Thawne disappearance.
 * The first being blue that appeared in.
