Teri Hatcher and Kevin Sorbo make their debuts in Supergirl as Mon-El’s parents, Rhea and Lar Gand. Now Lar Gand is Mon-El’s real name from the comics. We learn through Supergirl that Mon-El is the Prince of Daxamite and we got the full backstory of how he came to Earth. Unfortunately this did changed everything between Supergirl and Mon-El as he lied to her about everything. Jeremiah Danvers alluded to this and how Kara would react and we got our answer.
Basically this was an opening hook, but this episode was actually Winn-centric as I knew going into this. The focus was on Winn and Lyra, along with James and Alex. The reason Kara got little emphasis was because she was doing the musical crossover with the Flash during this and Exodus hence why Alex and Winn got plenty of screentime.
Also it seemed like they don’t know what to do with Kara other than her romance with Mon-El or how to integrate her into other storylines. This episode was about betrayal and trust that was experienced by both Kara and Winn, who learns that Lyra has been using him and did this sort of thing for 9 months.
In the end, Winn did forgave Lyra while Kara was not as forgiving or understanding towards Mon-El despite their scenes after the spaceship nor involvements from Alex and Winn. It makes the scenes between Kara and Mon-El pointless. The end of the episode has the appearance of the Music Meister, played by Darren Criss, who uses his power to render Kara unconscious and breach through the dimensional barrier while Kara is in the musical world of the 1940’s ready to sing her song.
