"I always knew that I was a girl. My parents were amazing. They affirmed my authentic self, and helped me transition young, and I've always been able to be open about who I was in Parthas. I'm not saying it was easy; there were definitely people who didn't understand. But the town's ethos of inclusion is strong, and I think if I grew up anywhere else, it would have been a lot tougher."
Kara joins Nia on a trip to Nia's hometown to visit her family during the town's annual Harvest Festival. While home, Nia's mother encourages her daughter to embrace her destiny. Meanwhile, Alex deals with a street drug that is turning people violent and giving them temporary superpowers.[src]
Brainy identifies the source of radiation in the Rage drug as gamma rays, which, in Marvel comics, is the same source that turned Bruce Banner into the Incredible Hulk.
Lena recognizes Parthas, Nia's hometown, as a word of Irish origin meaning "Paradise". Lena's actress, Katie McGrath, is herself Irish, and her native accent has briefly slipped out in several previous episodes.
Throughout the episode, there are many references to the 1991 film Terminator 2: Judgment Day, and Alex, Kara, and J'onn even begin watching it at the end of the episode.
When witnessing Spencer's rage transformation, Kevin Huggins says he looks "like Hagrid on steroids", referring to the character from Harry Potter.
Alex is shown to have a more aggressive approach towards aliens, ostensibly since her memories of Kara's powers were erased and she doesn't remember growing up with an alien for an adopted sister. However, this is a plot hole since Alex's views were also heavily influenced by Maggie's perspective,[1] and J'onn's powers did not alter her memories of their relationship.
