We open up this episode to how Supergirl began and that is her saving the plane that had Alex on it. This save had a profound affect on a passenger who was drowning his sorrows when the plane started going down and saw Supergirl on the wing after saving the plane and flying away.
Back to the present day, Sam is watching Ruby’s soccer match while also trying to complete a merger. Sam is then approached by a lady saying Ruby is special and invites her to attend a meeting. Before leaving, the woman hands Sam a pamphlet with a Kryptonian symbol on it. Later, Sam meets up with Lena at L Corp. to talk about the merger. Kara has also tagged along and notices the pamphlet and reads it with great interest and asks to keep it.
At CatCo, Kara is doing some research and notes that there is a meeting with this group that night. Kara, Winn and James goes to the meeting and sees the man that Kara saved from the plane. The three listen to this man, who we later learn is named Thomas Coville, welcoming people to the Children of Rao and it is made up of a group of people who were all saved by Supergirl. Kara remembers saving one young woman, Olivia (Sofia Vassilieva), who shares her story and how it changed her life. Coville then starts to recite a Kryptonian prayer that causes Kara to remember her mom reciting the same thing. Kara tells James and Winn that Coville is twisting the teachings of Rao.
Later that night during a girls night at Kara’s, Sam is discussing her struggles at juggling being a single working mom. Sam mentions that Alex and Maggie will understand once they have children. Alex states that two don’t plan on having children but we clearly see that she is having a hard time believing that. The night is cut short for Kara with the sounds of sirens.
Kara arrives at the scene of a bad warehouse fire. A young man falls through the crumbling roof and into the flames but is saved by Supergirl. Olivia comes rushing to the man saying he is now one of them. Supergirl cannot believe someone deliberately set a fire so they could be saved by her. The man is arrested and Maggie tells Kara that they can’t arrest Coville because he has not done anything illegal.
The next day, Kara returns to Coville’s church on the pretense of doing a story. However, Coville knows Kara is Supergirl because of her eyes. Kara tries to get Coville to stop his people from endangering themselves and others in her name. Coville spouts all he is doing is spreading the word of Rao but Kara tells him he is twisting it. Coville then shows Kara a Kryptonian artifact he found and tries to convince Kara of the work he is doing. Kara isn’t happy with Coville and grabs the artifact and leaves.
In James’ office, Kara is struggling at being seen as a God but he points out that there is nothing wrong in people having someone to believe in. When Kara shows James’ the Kryptonian artifact, it turns on and a hologram appears. Kara knows what it is and gets Winn to track Betahedron signature. Apparently this relates to a Kryptonian probe that is sent out to teach people about Krypton. And Coville has this Betahedron in his possession.
Elsewhere, Sam’s struggles with work-balance rears its ugly head when she can’t help Ruby rehearse a song for an upcoming school concert. Sam has to deal with a work emergency that would endanger the merger she completed that she manages to resolve. Lena pays Sam a visit and tells her not to be so hard on herself about her perceived failings as a mother.
The DEO learn that Coville plans on blowing up the Betahedron at National City University’s hockey rink so that Supergirl will save everyone thus gaining Coville more followers.
Supergirl arrives and begs Coville to stop the Betahedron but he won’t listen as he is firm in his beliefs. As Supergirl approaches the Betahedron, she becomes overwhelmed because there is Kryptonite in it. When Coville’s followers sees that Supergirl cannot save them, they flee. Coville then tries to turn off the Betahedron does nothing. Alex arrives and grabs the Kryptonite and throws it away. Unfortunately, Kara is too weak to fly away with it but is strong enough to use her heat vision to dig a very big hole in the ground that Alex and Coville push the Betahedron in it and it safely blows up.
Kara visits Coville in prison and wants to know if he will save who she really is. Coville tells Kara that he doesn’t remember the name that she used so it looks like her secret is safe. Coville mentions when he first saw Kara, she saw clarity and determination in her eyes but now sees that she is lost. Coville tells her he will continue to pray to her and will also pray for her.
The ladies of Supergirl attend Ruby’s school concert in support of Sam. The ladies are treated to a dance performed by group of girls dressed as Supergirl. Ruby then performs “Pure Imagination” and this causes Alex to get all emotional where she has to leave.
Outside, Alex tells Kara how Maggie doesn’t want children but admits she wants to be a mom. However, Alex loves Maggie but doesn’t know how to be with her and also the desire to be a mom.
Alex returns home and hops into bed with Maggie who scoots over of a snuggle. We see Alex struggle with how to tell Maggie or even if to tell her.
We also see Kara say the Rao prayer with the AI hologram of her mom.
And back at the Arias’, Sam is preparing for a bath and when she sees her reflection, her face and arms are filled with Kryptonian symbols. Then a hooded figure appears (Anjali Jay) and menting the name “Reign”. Ruby screams her mom’s name and when she looks up, everything is back to normal.
We then flashback 22 hours earlier and the consequence of pushing the Betahedron underneath the Earth. Apparently the explosion caused Reign’s ship to power back on and someone in one of the pods pushes its hand along the glass. Was it that hooded figure? I am not sure. Also, I really like Sam and her relationship with Ruby as well as her struggles to be a good mom. Hopefully, there is a way that Reign can be redeemed.
