- Title: Supergirl – Dark Side of the Moon
- wiki: link
Searching for substance that can separate Reign (Odette Annable) from Sam leads Kara (Melissa Benoist) and Mon-El (Chris Wood) to an asteroid that isn’t an asteroid at all. What they find is the Kryptonian city of Argo floating in space thanks to the use of the very same material they need to stop Reign. The season finally offers a payoff to the show recasting Kara’s mother as Supergirl encounters Alura Zor-El (Erica Durance) alive and well on Argo. Despite the citizens needing the precious material to stay safe in space, Alura and Kara argue decisively for a sample to save the Earth. Kara meeting the council also answers the question to just who is behind Reign’s creation, although only for the audience.
Supergirl returns at the last second with the prize, but the question is why did Reign’s creator allow Kara to leave with the one thing that could stop her plans for Earth? The episode’s subplots focus on Lena (Katie McGrath) struggling with a difficult decision where her friend is concerned and an attack on Alex‘s (Chyler Leigh) life while she is watching Ruby (Emma Tremblay). Both fit into the larger arcs for both characters while the later also finally allows Ruby and Finn (Jeremy Jordan) to bond over the shared experiences of their parents trying to kill them.
