Did You Know?


This is Cisco's first appearance on Supergirl making him the second Arrowverse character to appear on all four of The CW's DC shows, ("Arrow" (2012) {The Man Under the Hood (#2.19)}), ("The Flash" (2014)), ("Legends of Tomorrow" (2016) {Fail-Safe (#1.5)}), & ("Supergirl" (2015) {Medusa (#2.8)}) See more »


At the beginning of the episode, James and Winn argue about who gets to tell Kara that James is the Guardian; why they're bothering to whisper is a mystery, since they both know she has superhuman hearing. Even more odd is the fact that she doesn't seem to hear them, even though a similar whispered conversation in "Supergirl: Blood Bonds" is how she discovered J'onn's real identity. See more »
